PROLOGUE

General Facts about NTPEP Reports: NTPEP Reports contain data collected according to laboratory testing and field evaluation protocols

developed through consensus-based decision by the AASHTO’s NTPEP Oversight Committee.These test and evaluation protocols are described in the Project Work Plan (see NTPEP website).

Products are voluntarily submitted by manufacturers for testing by NTPEP. Testing fees are assessedfrom manufacturers to reimburse AASHTO member departments for conducting testing and to reportresults. AASHTO member departments provide a voluntary yearly contribution to support theadministrative functions of NTPEP.

AASHTO/NTPEP does not endorse any manufacturer’s product over another. Use of certainproprietary products as “primary products” does not constitute endorsement of those products.

AASHTO/NTPEP does not issue product approval or disapproval; rather, test data are furnished forthe User to make judgment for product prequalification or approval for their transportation agency.

Guidelines for Proper Use of NTPEP Results: The User is urged to carefully read any introductory notes at the beginning of this Report, and also to

consider any special clauses, footnotes or conditions which may apply to any test reported herein.Any of these notes may be relevant to the proper use of NTPEP test data.

The User of this Report must be sufficiently familiar with the product performance requirementsand/or (standard) specification of their agency in order to determine which test data are relevant tomeeting those qualifying factors.

NTPEP test data is intended to be predictive of actual product performance. Where a transportationagency has successful historical experience with a given product, it is suggested to factor thatprecedence in granting or withholding product approval or prequalification.

NTPEP Report Special Advisory for Geosynthetic Reinforcement (REGEO): This report contains product data that are intended to be applied to a product line, based on the test

results obtained for specific products that are used to represent the product line for the purposes ofNTPEP testing. It is expected that the User will estimate the properties of specific products in theline not specifically tested through interpolation or a lower or upper bound approach.

It is intended that this data be used by the User to add products to their Qualified Products orApproved Products List, and/or to develop geosynthetic reinforcement strength design parameters inaccordance with AASHTO, FHWA, or other widely accepted design specifications/guidelines. It isalso intended that the User will conduct further, but limited, evaluation and testing of the productsidentified in this report for product acceptance purposes to verify product quality.

Products included in this report must be resubmitted to NTPEP every three (3) years for a qualityassurance evaluation and every six (6) years for a full qualification evaluation in accordance with thework plan. Hence, all product test results included in this Report supersede data provided in previousEditions of this report.

The User is guided to read the document entitled “Use and Application of NTPEP GeosyntheticReinforcement Test Results” (see NTPEP website) for instructions and background on how to applythe results of the data contained in this report.

Executive Summary

This test report provides data that can be used to characterize the short-term and long-term tensilestrength the Linear Composites Limited polyester, Linear Low Density Polyethylene (LLDPE)coated geogrid reinforcement product lines using testing conducted on representative productswithin the product line. The purpose of this report is to provide data for product qualificationpurposes.

The test results contained herein were obtained in accordance with WSDOT Standard PracticeT925 and the NTPEP work plan (see www.NTPEP.org) and can be used to determine the long-term strength of the geosynthetic reinforcement, including the long-term strength reductionfactors RFID, RFCR, and RFD, and also used to determine low strain creep stiffness values. Alltesting reported herein was performed on the materials tested in the direction of manufacture, i.e.,the machine direction.

Description of Product Lines: All of the reinforcement products submitted by LinearComposites to NTPEP for testing were originally submitted as one product line. However, basedon preliminary test results, it became apparent the ParaGrid products needed to be treatedseparately from the ParaWeb/ParaLink products. Hence, these two subsets of the submittedproducts were treated as two separate product lines.

The product lines evaluated include the following specific polyester, Linear Low DensityPolyethylene (LLDPE) coated geogrid reinforcement products:

Product Line 1: Linear Composites ParaWeb 2S/2D/2E 30, ParaWeb 2S/2D/2E 40, ParaWeb2S/2D/2E 50, ParaWeb 2S/2D/2E 75, ParaWeb 2S/2D/2E 100, ParaWeb MS/MD/ME 36,ParaWeb MS/MD/ME 45, ParaWeb MS/MD/ME 54, ParaWeb MS/MD/ME 63, ParaWebParaLink 200, ParaLink 300, ParaLink 350, ParaLink 400, ParaLink 500, ParaLink 600, ParaLink700, ParaLink 800, ParaLink 900, ParaLink 1000, ParaLink 1100, ParaLink 1200, ParaLink 1300& ParaLink 1350. Linear Composites also manufacturers ParaLink products intermediate to theproducts listed here as part of this product line, though the intermediate products were notspecifically identified in the list of submitted products.

Product Line 2: Linear Composites ParaGrid 30/05, ParaGrid 40/05, ParaGrid 50/05, ParaGrid60/05, ParaGrid 70/05, ParaGrid 80/05, ParaGrid 90/05, ParaGrid 100/05, ParaGrid 110/05,ParaGrid 125/05, ParaGrid 150/05, ParaGrid 175/05, ParaGrid 180/05 & ParaGrid 200/05.

Product line 1 was represented through testing of Linear Composites ParaWeb 2E 30, ParaWeb2E 50, ParaWeb 2S 100, ParaLink 350 and ParaLink 1300. ParaWeb 2S/2D/2E & ParaWebMS/MD/ME products are six styles of polymer straps which differ only in dimensionaltolerances specific to strap width and coating thickness. The “2” and “M” designations refer tothe width of the strap. ParaWeb “2” products are approximately 3.5 inches wide while ParaWeb“M” products are approximately two inches wide. The “S”, “D” and “E” designations refer tothe thickness of the LLDPE coating with “S” having the thickest coating and “E” having thethinnest coating. Still, the production process itself remains the same for all types and it is thisaspect of same production parameters that enables all styles to be considered one type of product.

Product line 2 was represented through testing of Linear Composites ParaGrid 30/05, ParaGrid50/05 and ParaGrid 200/05. Samples of these eight products were taken by an independentsampler on behalf of NTPEP on November 24, 2008, at the Linear Composites manufacturingplant located in West Yorkshire, UK.

Statistical Validation of Use of SIM and Validation of Product Line: The creep rupture testresults obtained were statistically evaluated in accordance with T925 to assess the validity ofusing SIM to extend the creep rupture data and to assess the validity of treating the productssubmitted as a single product line. The following was verified:

i. The SIM tests used to extrapolate creep test results were characterized by datastatistically consistent with conventional creep tests conducted at the referencetemperature up to 10,000 hours (see Figures F-49 and F-50 in Appendix F fordetails).

ii. Based on the creep data obtained for all the products tested, theParaWeb/ParaLink products statistically qualify to be a product line and theParaGrid products statistically qualify to be a product line. However, all of theproducts together (ParaWeb, ParaLink and ParaGrid) do not statistically qualify tobe a product line. Therefore, the products submitted were split into two productlines as described above. Within the product lines as defined herein, all of theproducts within those lines can be represented using test results fromrepresentative products in the product line (see Figures F-51 thru F-58 inAppendix F for details). Recommendations on application of the representativeproduct data to the rest of the product line for installation damage, durability andcreep stiffness are provided in their respective report sections and summarizedbelow in this executive summary.

Test Results for Tult: All wide width test results (ASTM D6637) obtained for this product linethrough the NTPEP testing were greater than the minimum average roll values (MARV’s)provided by the manufacturer (see Tables 3-1 thru 3-3).

Test Results for RFID: Installation damage testing on the ParaWeb / ParaLink product lineresulted in values of RFID that ranged as follows:

RFID = 1.00 to 1.06

Installation damage testing on the ParaGrid product line resulted in values of RFID that ranged asfollows:

RFID = 1.00 to 1.09

The highest values of RFID occurred when the coarse gravel gradation was used.

The values of RFID for all of the products tested did demonstrate a trend of decreasing RFID asproduct unit weight/tensile strength increases, at least for the coarse gravel gradation, that wouldallow interpolation of RFID to products not tested. Therefore, interpolation of these test results toproducts in the line not tested is feasible. This trend was not as clear for the other, less coarse,


6

gradations. In general, as the test material gradation becomes more coarse, the value of RFID

increased. Therefore, interpolation of this data to intermediate gradations also appears to befeasible. See Tables 4-3 and 4-5 and Figures 4-5 through 4-12 for details. Laboratoryinstallation damage testing in accordance with ISO/EN 10722 was not conducted.

It should be noted that the installation damage strength retained and RFID values provided in thisreport reflect good geosynthetic installation practices that will keep damage to the geosynthetic toa reasonable minimum. The spreading and compaction equipment used in the installationdamage testing reflects typical tracked or moderate tire pressure equipment. Actual RFID valuescould be higher if the spreading or compacting equipment tires or tracks are allowed to be indirect contact with the geosynthetic before or during fill placement and compaction, if thethickness of the fill material between the equipment tires or tracks is inadequate (especially forhigh tire pressure equipment such as dump trucks), or if excessive rutting of the first lift of soilover the geosynthetic (e.g., due to soft subgrade soil) is allowed to occur.

Test Results for RFCR: The creep rupture testing conducted indicates that the following valueof RFCR may be used for the ParaWeb / ParaLink product line:

RFCR = 1.36

The creep rupture testing conducted indicates that the following value of RFCR may be used forthe ParaGrid product line:

RFCR = 1.39

These values of RFCR are applicable to a 75 year life at 68o F (20o C), and may be used tocharacterize the full product line as defined herein. See Figures 5-1 and 5-2 for detailed creeprupture envelope or to obtain values for other design lives.

Test Results for RFD: The chemical durability index testing results meet the requirements inWSDOT T925 to allow use of a default reduction factor for RFD. See Table 6-2 for specific testresults, and see WSDOT T925 or the document entitled “Use and Application of NTPEPGeosynthetic Reinforcement Test Results” (www.NTPEP.org) for recommended defaultreduction factors for RFD. The UV test results (ASTM D4355) for the ParaWeb / ParaLinkproduct line, as represented by the lightest weight product in the line, indicate a strength retainedat 500 hours in the weatherometer of 98%. The UV test results (ASTM D4355) for the ParaGridproduct line, as represented by the lightest weight product in the line, indicate a strength retainedat 500 hours in the weatherometer of 72%. These values of UV strength retained should beconsidered to be lower bound values for each product line.

Test Results for Creep Stiffness: The 1000 hr, 2% strain secant stiffness (J2%,1000hr) test resultsfor the ParaWeb / ParaLink product line ranged from 40,853 lb/rib for the lowest strength style to133,159 lb/rib for the highest strength style. Due to the strong linear relationship between creepstiffness and the short-term tensile strength (Tlot), the 1000 hr, 2% strain secant stiffness can,thus, be reasonably expressed for any product in the ParaWeb / ParaLink product line as:


7

J2%,1000 hr = (3.6167 *Tlot) + 14,529

The 1000 hr, 2% strain secant stiffness (J2%,1000hr) test results for the ParaGrid product lineranged from 16,727 lb/ft for the lowest strength style to 80,743 lb/ft for the highest strength style.Due to the strong linear relationship between creep stiffness and the short-term tensile strength(Tlot), the 1000 hr, 2% strain secant stiffness can, thus, be reasonably expressed for any productin the ParaGrid product line as:

J2%,1000 hr = (4.9331 *Tlot) + 3336.7

Where, Tlot is the roll/lot specific single rib tensile strength per ASTM D6637. See Tables 7-3and 7-4 and Figures 7-1 and 7-2 for details. Note that once the stiffness is determined from thisequation, an equivalent MARV for this property can be determined by multiplying the stiffnessby the ratio of TMARV/Tlot.

1.0 Product Line Description and Testing Strategy

1.1 Product Description

The Linear Composites family of geogrids are high-strength, Linear Low Density Polyethylene(LLDPE) coated straps. The product lines evaluated consists of the products as manufactured byLinear Composites Limited listed in Table 1-1. Initially, these products were submitted as oneproduct line. Based on preliminary creep testing, it became apparent that these products neededto be split into two product lines as shown in Table 1-1.

Table 1-1. Product designations included in product line.

ParaGrid 200/05

Note: ParaWeb 2S/2D/2E & ParaWeb MS/MD/ME products are six styles of polymer strapswhich differ only in dimensional tolerances specific to strap width and coating thickness. The“2” and “M” designations refer to the width of the strap. ParaWeb “2” products areapproximately 3.5 inches wide while ParaWeb “M” products are approximately two inches wide.The “S”, “D” and “E” designations refer to the thickness of the LLDPE coating with “S” havingthe thickest coating and “E” having the thinnest coating. Still, the production process itselfremains the same for all types and it is this aspect of same production parameters that enables allstyles to be considered one type of product. For the ParaLink products, Linear Composites alsomanufactures products intermediate to the products listed in Table 1-1. The detailed list of theintermediate products was not provided.

The scope of the evaluation is limited to the strength in the machine direction (MD). The cross-machine direction (XD) was not specifically evaluated.

1.2 Product Line Testing Approach

Product line 1 was represented through testing of Linear Composites ParaWeb 2E 30, ParaWeb2E 50, ParaWeb 2S 100, ParaLink 350 and ParaLink 1300. Product line 2 was representedthrough testing of Linear Composites ParaGrid 30/05, ParaGrid 50/05 and ParaGrid 200/05.ParaWeb 2E 50 was used as the primary product for the ParaWeb / ParaLink product linecharacterization purposes and ParaGrid 50/05 was used as the primary product for the ParaGridproduct line characterization purposes (i.e., the baseline to which the other products werecompared). The “E” designation products were selected for testing because they had the thinnestcoating an would be most susceptible to installation damage and UV damage. Therefore use ofthe “E” products would provide the most conservative assessment for the product line. Samplesof these three products were taken by an independent sampler on behalf of NTPEP on November24, 2008, at the Linear Composites manufacturing plant located in West Yorkshire, UK.

Photographs of the individual products actually tested are provided in figures 1-1 through 1-8.

2.0 Product Polymer, Geometry, and Manufacturing Information

2.1 Product/Polymer Descriptors

Yarns used in all Linear Composites geogrids are high molecular weight, low CEG, hightenacity polyester (PET). Source of Yarns – Proprietary. Coating used in all Linear Compositesgeogrids is a Linear Low Density Polyethylene (LLDPE)-based coating with no post-consumerrecycled materials. Source of Coating – Proprietary.

For the PET yarns, key descriptors include minimum production number average molecularweight (GRI-GG7 and ASTM D 4603) and maximum carboxyl end group content (GRI-GG8):

o Minimum Molecular Weight > 25,000 (Typical values are 34,335 and 34,632)o Maximum CEG < 30 (Typical values are 10.9 and 12.1)o % of regrind used in product: 0%.o % of post-consumer recycled material by weight: 0%

2.2 Geometric Properties of Geogrids

Rib width, spacing, thickness, and product weight/unit area vary depending on geogrid style.While such data are generally not used for design, it can be useful for identification purposes, andto be able to detect any changes in the product. Measurements of geogrid rib spacing are alsoused to convert tensile test results (i.e., load at peak strength, Tult, and load at a specified strain toobtain stiffness, J) to a load per unit width value (i.e., lbs/ft or kN/m). Detailed measurementresults, as well as the typical values supplied by the manufacturer for each product, are providedin Appendix B, Section B.1. Note that the ParaWeb products are not a geogrid, but instead are apolymer strap.

2.3 Product Production Data and Manufacturing Quality Control

Geogrid roll sizes and weights, lot sizes, and a summary of the manufacturer’s quality controlprogram are provided in Appendix B, Sections B.2 and B.3. Such information can be useful inworking with the manufacturer if product quality issues occur.

3.0 Wide Width Tensile Strength Data

Minimum average roll values supplied by the manufacturer and test results obtained on theproducts used to represent the product lines in this NTPEP testing program are provided inTables 3-1 thru 3-3. Wide width tensile tests were conducted in accordance with ASTM D6637.The measured geogrid dimensions discussed in Section 2 and provided in Appendix B, SectionB.1, were used to convert test loads to load per unit width values. Note that the independentlymeasured Tult values only indicate that the sampled products have a tensile strength that exceedsthe Manufacturer’s minimum average roll values (MARV’s). As such, these independentlymeasured Tult values should not be used directly for design purposes. However, theseindependently measured Tult test results have been used as roll specific tensile strengths forcomparison to installation damage and creep test results. Detailed test results are provided inAppendix C.

4.2 Installation Damage Full Scale Field Exposure Procedures and MaterialsUsed

Three “standard” soils were used for the field exposure of the geogrid samples to installationdamage. Soil gradation curves for each soil are provided in Figure 4-1. Photographs of each soilillustrating particle angularity are provided in figures 4-2 through 4-4. LA Abrasion testsconducted to characterize the backfill materials indicted a maximum loss of 21%, which is wellwithin the requirements stated in T925. Note that the photograph of the Type 2 soil only showsthe coarser particles since the percentage of sand in that soil is relatively small, and the sandparticles have slipped into the voids in this poorly graded gravel just below the stockpile surfaceat the time this photograph was taken.

The approach specifically used for applying installation damage to the geosynthetic samples thatallows for exhumation of the test samples while avoiding unintended damage was initiallydeveloped by Watts and Brady1 of the Transport Research Laboratory (TRL) in the UnitedKingdom. The procedure generally conforms to T925 and ASTM D 5818 requirements.

Since compaction typically occurs parallel to the face of retaining walls and the contour lines ofslopes, the machine direction was placed perpendicular to the running direction of thecompaction equipment. To initiate the exposure procedure, four steel plates each measuring 42-inches x 52-inches (1.07 m x 1.32 m), equipped with lifting chains, were placed on a flat cleansurface of hardened limestone rock. The longer side of the plates is parallel to the runningdirection of the compaction equipment. A layer of soil/aggregate was then placed over theadjacent plates to an approximate compacted thickness of 8 inches (0.18 m). Next, each of fourcoupons of the tested geosynthetic sample was placed on the compacted soil over an areacorresponding to an underlying steel plate. To complete the installation, the second layer of soilwas placed over the coupons using spreading equipment and compacted to a thickness of 8inches (0.18 m) using a vibratory compactor. The spreading equipment used included a wheeledfront end loader and a 10,000 lb single drum vibratory roller with pneumatic rear wheels. Thefront end loader was allowed to spread the aggregate by driving over the geosynthetic with an 8inch aggregate lift between the wheels and the geosynthetic.

The following construction quality control measures were followed during exposure: Proctor and sieve analyses were performed on each soil/aggregate, when possible.

(Proctors could not be performed on Gradations 1 and 2.) Lift thickness measurements were made after soil/aggregate compaction. When possible, moisture and density measurements were made on each lift using a

nuclear density gage to confirm that densities >90% of modified Proctor (per ASTM D1557) were being achieved.

To exhume the geosynthetic, railroad ties were removed and one end of each plate was raisedwith lifting chains. After raising the plate to about 45, soil located near the bottom of theleaning plate was removed and, if necessary, the plate was struck with a sledgehammer to loosen

the fill. The covering soil/aggregate was then carefully removed from the surface while “rolling”the geosynthetic away from the underlying soil/aggregate. This procedure assured a minimum ofexhumation stress. Photographs of the installation damage field exposures are provided inAppendix D. A detailed tabulation of each soil gradation is provided in Appendix D, Table D-10.

4.3 Summary of Installation Damage Full Scale Field Exposure Test Results

The roll specific ultimate tensile strength (ASTM D6637) test results for the baseline, Tlot (i.e.,undamaged tensile strength tested prior to sample installation in the ground) and the ultimatetensile strength of the installation damaged geogrid samples, Tdam, are provided in Tables 4-2 and4-4. RFID, calculated using the results shown in Tables 4-2 and 4-4, are summarized in Tables 4-3 and 4-5. Strength retained is calculated as the ratio of the average exhumed strength Tdam

divided by the average baseline strength Tlot for the product sample. RFID is the inverse of theretained strength (i.e. 1 / 0.917 = 1.09). Detailed test results for each specimen tested areprovided in Appendix D, Tables D-1 through D-18.

4.4 Estimating RFID for Specific Soils or for Products not Tested

In general, as the test material gradation becomes more coarse, the value of strength retaineddecreased (i.e., RFID increased). Trend lines plotted in Figures 4-5 and 4-6 for the mean, upperbound and lower bound for all the installation damage data obtained for both product linesillustrate the general trend of the installation damage data with regard to soil d50 size.Interpolation of this data to intermediate gradations appears to be feasible based on these testresults, though the scatter in that trend should be recognized when estimating values of RFID for


25

specific soils. In general, the amount of strength loss due to installation damage for theParaWeb/ParaLink products was very small and a lower bound approach to establishing values ofRFID for the full range of gradations is also a reasonable approach to take for Product Line 1. ForProduct Line 2, the losses are a little larger, and the trend in the relationship between RFID andd50 is stronger.

The Linear Composites ParaWeb / ParaLink and ParaGrid product lines generally exhibitedmoderately strong relationships between the weight or the tensile strength of the product and thestrength retained after installation damage, at least for gradation 1. The values of RFID generallydecreased (i.e., strength retained increased) as product weight/strength increased (see figures 4-7through 4-12). Therefore, interpolation of these test results to products in the line not testedbased on product weight or strength may be feasible for the coarsest soil tested, though cautionshould be exercised and appropriate judgment applied to insure a safe estimate of RFID eachproduct.

It should be noted that the installation damage strength retained and RFID values provided in thisreport reflect good geosynthetic installation practices that will keep damage to the geosynthetic toa reasonable minimum. The spreading and compaction equipment used in the installationdamage testing reflects typical tracked or moderate tire pressure equipment. Actual RFID valuescould be higher if the spreading or compacting equipment tires or tracks are allowed to be indirect contact with the geosynthetic before or during fill placement and compaction, if thethickness of the fill material between the equipment tires or tracks is inadequate (especially forhigh tire pressure equipment such as dump trucks), or if excessive rutting of the first lift of soilover the geosynthetic (e.g., due to soft subgrade soil) is allowed to occur.

5.0 Creep Rupture Data (RFCR)

5.1 Creep Rupture Test Program

Creep testing and interpretation has been conducted in accordance with WSDOT StandardPractice T925, Appendices B and C. A baseline (i.e., reference) temperature of 68o F (20o C)was used. ParaWeb 50 was used as the primary product for the ParaWeb / ParaLink product lineto establish the creep rupture envelope, with limited creep testing of the other ParaWeb /ParaLink products (i.e., ParaWeb 30, ParaWeb 100, ParaLink 350 and ParaLink 1300) to verifythe ability to interpolate creep rupture behavior to the ParaWeb / ParaLink products notspecifically tested (i.e., to treat all the products submitted for evaluation as a product line perT925 and the NTPEP work plan).

It was initially attempted to include the ParaGrid products with the ParaWeb/ParaLink productsas one product line. However, the ParaWeb/ParaLink and ParaGrid product creep test results didnot meet the qualification requirements for “family consistency” in creep behavior as outlined inWSDOT Standard Practice T925 and the NTPEP work plan. Therefore, the ParaGrid productsmust be considered as a separate product family with respect to creep rupture. ParaGrid 50/05was used as the primary product for the ParaGrid product line to establish the creep ruptureenvelope, with limited creep testing of the other ParaGrid (i.e., ParaGrid 30/05 and ParaGrid200/05) to verify the ability to interpolate creep rupture behavior to the ParaGrid products notspecifically tested (i.e., to treat all the products submitted for evaluation as a product line perT925 and the NTPEP work plan).

The creep rupture testing program is summarized in tables 5-1 and 5-2. Creep testing wasconducted using both ASTM D5262 (termed “conventional” creep testing) and ASTM D6992(i.e., the Stepped Isothermal Method - SIM). A limited number (6) of tests using ASTM D5262,conducted only at the reference temperature of 68o F (20o C) for up to a minimum time of 10,000hrs were used for comparison purposes to verify the accuracy of the SIM creep tests.

5.2 Baseline Tensile Strength Test Results

The width, spacing and strength of the individual sample ribs prohibited creep rupture testingfrom being performed on multi-rib specimens. Therefore, all conventional creep testing (ASTMD5262) and accelerated creep testing via SIM (ASTM D6992) were performed on single ribspecimens. Sample specific geogrid dimensions were used to convert tensile test loads to loadper unit width values for ParaLink and ParaGrid products only. The tensile test specimens testedwere taken from the same rolls of material that were used for the creep testing. The measuredgeogrid dimensions discussed in Section 2 and provided in Appendix B, Section B.1, were usedto convert tensile test loads to load per unit width values.

5.3.1 Statistical Validation to Allow the Use of SIM Data to Establish RuptureEnvelope.

Details of the confidence limits evaluation conducted in accordance with T925 are containedin Appendix F. Figures F-49 and F-50 provides a plot of the creep rupture envelopes with theconfidence limits and the rupture envelopes for the conventional creep and SIM creep datafor each of the ParaWeb / ParaLink and ParaGrid product lines, illustrating this statisticaltest. Detailed calculation results for this statistical analysis are provided in Tables F-2 and F-3, and summarized in Tables F-14 and F-15. The results indicate that the SIM data meet thestatistical validation requirements in T925 (i.e., the SIM rupture envelope is within thespecified 90% confidence limits of the “conventional” creep rupture data) for each productline. Thus, the conventional and accelerated (SIM) data may be used together to construct thecharacteristic creep rupture curve of the primary product, and SIM data may also be used forcreep testing of the other products within each product line to evaluate the potential toconstruct a composite creep curve for each product line.

5.3.2 Statistical Validation to Allow the Use of Composite Rupture Envelope forParaWeb / ParaLink and ParaGrid Products as one Product Line

Details of the confidence limits evaluation for the ParaWeb / ParaLink / ParaGrid productline conducted in accordance with T925 are contained in Appendix F. Figures F-51 thru F-56provide plots of the creep rupture envelope with the confidence limits and the ruptureenvelopes for the primary product and the other tested products (i.e., ParaWeb 30, ParaWeb100, ParaLink 350, ParaLink 1300, ParaGrid 30/05 and ParaGrid 200/05), illustrating thisstatistical test. Detailed calculation results for this statistical analysis are provided in tablesF-4 through F-9, and summarized in Table F-16. The results indicate that the ruptureenvelopes for ParaWeb 30, ParaWeb 100, ParaLink 350 and ParaLink 1300 are within thespecified 90% confidence limits of the primary product (i.e., ParaWeb 50) creep rupture data,meeting T925 requirements. However, the results indicate that the rupture envelopes forParaGrid 30/05 and ParaGrid 200/05 are not within the specified 90% confidence limits ofthe primary product (i.e., ParaWeb 50) creep rupture data. Thus, the ParaGrid products mustbe considered as a separate product family with respect to creep rupture.

5.3.3 Statistical Validation to Allow the Use of Composite Rupture Envelope forParaWeb / ParaLink Product Line

Details of the confidence limits evaluation for the ParaWeb / ParaLink product lineconducted in accordance with T925 are contained in Appendix F. Figures F-51 thru F-54provides plots of the creep rupture envelope with the confidence limits and the ruptureenvelopes for the primary product and the other tested products (i.e., ParaWeb 30, ParaWeb100, ParaLink 350 and ParaLink 1300), illustrating this statistical test. Detailed calculationresults for this statistical analysis are provided in tables F-4 through F-7, and summarized inTable F-17. The results indicate that the rupture envelopes for ParaWeb 30, ParaWeb 100,ParaLink 350 and ParaLink 1300 are within the specified 90% confidence limits of theprimary product (i.e., ParaWeb 50) creep rupture data, meeting T925 requirements. Thus, allthe ParaWeb / ParaLink products tested (i.e., ParaWeb 30, ParaWeb 50, ParaWeb 100,ParaLink 350 and ParaLink 1300) can be used to construct a composite creep ruptureenvelope representing the entire product line. The calculation results for the statisticalanalysis and regression to create the full composite creep curve are provided in Table F-12.

5.3.4 Statistical Validation to Allow the Use of Composite Rupture Envelope forParaGrid Product Line

As stated previously, the ParaGrid products were not within the specified 90% confidencelimits of the primary product of the ParaWeb / ParaLink (i.e., ParaWeb 50) creep rupture dataand must be considered as a separate product family with respect to creep rupture. Details ofthe confidence limits evaluation for the ParaGrid product line conducted in accordance withT925 are contained in Appendix F. Figures F-57 and F-58 provide plots of the creep ruptureenvelope with the confidence limits and the rupture envelopes for the primary product andthe other tested products (i.e., ParaGrid 30/05 and ParaGrid 200/05), illustrating thisstatistical test. Detailed calculation results for this statistical analysis are provided in tablesF-10 and F-11, and summarized in Table F-18. The results indicate that the rupture


38

envelopes for ParaGrid 30/05 and ParaGrid 200/05 are within the specified 90% confidencelimits of the primary product (i.e., ParaGrid 50/05) creep rupture data, meeting T925requirements. Thus, all the ParaGrid products tested (i.e., ParaGrid 30/05, ParaGrid 50/05and ParaGrid 200/05) can be used to construct a composite creep rupture enveloperepresenting the entire product line. The calculation results for the statistical analysis andregression to create the full composite creep curve are provided in Table F-13.

5.4 Creep Rupture Envelope Development and Determination of RFCR

In consideration of the statistical validation described in Section 5.3 of this report, two compositecreep rupture envelopes, using log-linear regression, were constructed as shown in Figures 5-1and 5-2. The mix of conventional and accelerated (SIM) creep rupture test data points meetsT925 requirements. Based on these plots of all data, the regressions of the data shows that the r2

values are 0.98 and 0.97 (see Tables F-12 and F-13 in Appendix F for details). Per T925, thisdegree of scatter in the data is acceptable for a composite rupture envelope.

The creep rupture envelope in Figure 5-1 should be considered valid for the ParaWeb / ParaLinkproduct line only. The creep rupture envelope for the ParaGrid product line is found in Figure 5-2. Since the temperature accelerated creep results produced through the SIM testing allowedtime shifting of the creep rupture data points to over 1,000,000 hours (i.e., 114 years), noextrapolation uncertainty factor in accordance with T925 need be applied. Table 5-7 provides theestimated value of RFCR for ParaWeb / ParaLink and ParaGrid product lines based on thereported testing for a period of long-term loading of up to 75 years. This rupture envelope can beused to determine RFCR for times other than 75 years, if desired.

6.0 Long-Term Durability Data (RFD)

6.1 Durability Test Program

Basic molecular properties and index tests relating to durability were evaluated, allowing a“default” RFD to be used in accordance with WSDOT Standard Practice T925, provided that thelong-term environment in which the geosynthetic is to be used is considered to be non-aggressivein accordance with the AASHTO LRFD Bridge Design Specifications and T925. A non-aggressive long-term environment is described in these documents as follows:

A soil ph of 4.5 to 9.0,

A maximum particle size of 0.75 inches or less unless installation damage effects arespecifically evaluated using full scale installation damage testing in accordance withASTM D 5818,

A soil organic content of 1% or less, and

An effective design temperature at the site of 86oF (30oC) or less.

Other specific soil/environmental conditions that could be of concern to consider the siteenvironment to be aggressive are discussed in Elias2.

The index properties/test results obtained can be related to long-term performance of the polymerthrough correlation to longer-term laboratory durability performance tests and long-termexperience. Note that long-term durability performance testing in accordance with T925 and theNTPEP work plan to allow direct calculation of RFD was not available from the manufacturer,nor evaluated as part of the testing program for this product line.

For polyester (PET) geosynthetics, key durability issues to address include hydrolysis andultraviolet (UV) oxidative degradation. To assess the potential for these types of degradation,index property tests to assess molecular weight, carboxyl end group content, and ultraviolet (UV)oxidative degradation are conducted on two yarns. Criteria for test results obtained each of thesetests are provided in T925 as well as the AASHTO LRFD Bridge Design Specifications.

The UV degradation tests were conducted on the lightest weight product in each product line(ParaWeb 30 and ParaGrid 30/05) as recommended in T925. Since UV degradation attacks fromthe surface of the geosynthetic, the heavier the product, the more resistant it will be to UVdegradation. Therefore, UV testing the lightest weight product should produce the mostconservative result.

The molecular weight and carboxyl end group content tests were conducted on two base yarns forthe product series. Since the two base yarns are used for all products in the ParaWeb, ParaLinknd ParaGrid products, these tests on the two base yarns will be applicable to all products in bothproduct lines.

Based on these test results, all products in the product line meet the minimum UV requirementshown in Table 6-2. Regarding hydrolysis resistance, these test results shown in Table 6-2indicate that this product line has adequate long-term resistance to hydrolysis to justify the use ofa default value for RFD, meeting the requirements in T925.

Note that while no specific tests, other than installation damage, were conducted to evaluate thedurability of the LLDPE coating, because the hydrolysis resistance characterization wasdetermined based on the base polymer, any potential coating degradation should have very littleeffect on the long-term durability of the geogrid product and the default value of RFD selected.Typically, a default value of 1.3 for RFD is selected. See WSDOT Standard Practice T925, or thedocument entitled “Use and Application of NTPEP Geosynthetic Reinforcement Test Results”(www.NTPEP.org), for guidance on the selection of a default value for RFD. Note that thecoating for these products as manufactured is unusually robust, as evidenced by the very lowsusceptibility of these products to installation damage. Because of this, it is likely that thecoating will reduce the exposure of the PET fibers to moisture, and thereby reduce the potentialamount of long=term degradation due to hydrolysis, possibly justifying the use of a lower defaultvalue for durability.

7.0 Low Strain Creep Stiffness Data

7.1 Low Strain Creep Stiffness Test Program

Creep stiffness testing was conducted in accordance with WSDOT Standard Practice T925 andthe NTPEP work plan. The creep stiffness determination was targeted to 2% strain at 1,000hours.

Four of the products selected to represent the ParaWeb / ParaLink product line (i.e., ParaWeb 30,ParaWeb 50, ParaLink 350 and ParaLink 1300) and all of the products selected to represent theParaGrid product line (i.e., ParaGrid 30/05, ParaGrid 50/05 and ParaGrid 200/05) were tested forcreep stiffness. Roll specific single rib short-term rapid loading tensile strength tests (Tlot) wereconducted for each product for correlation purposes and to calculate load levels. A total of nineRamp and Hold (R&H), 1,000 second creep tests, were conducted on each product. Threespecimens were R&H tested at each of the following stresses: 5, 10 and 20% of the ultimatetensile strength (UTS). A linear regression based on %UTS and % strain at 0.1 hour was used tonormalize strain curves to reduce the variability of the elastic portion of the strain curve. The %UTS required to obtain 2% strain at 1,000 hours was then determined. Three R&H tests and two1,000 hour conventional creep tests (ASTM D5262, but as modified for low strain in WSDOTStandard Practice T925 and using a single rib specimen) were conducted at this load. All testswere conducted at 68o F (20o C).

The values provided in Table 7-1 and 7-2 represent the baseline, roll specific, ultimate tensilestrength used to normalize the load level for the creep stiffness testing. Sample specific geogriddimensions were used to convert tensile test loads to load per unit width values.

7.3 Creep Stiffness Test Results

Detailed test results provided in Appendix H. Tables 7-3 and 7-4 provide summaries of the creepstiffness values obtained. Note that the creep stiffness values at 1,000 hours and 5%UTS,10%UTS and 20%UTS represent stiffness values at strains other than 2% strain. See AppendixH for details. Figures 7-1 and 7-2 shows the relationship between the measured tensile strengthand the creep stiffness. Considering the strong linear relationship between the creep stiffness andthe product tensile strength, interpolation to other products in the product line not tested todetermine creep stiffness values for those products is acceptable.

To obtain the minimum likely stiffness value for each product in consideration of the MARVtensile strength, multiply the stiffness value from the plot by the ratio of TMARV/Tlot. TMARV is theminimum tensile strength, as provided by the manufacturer, for each product in the product line.Tlot is the actual roll specific tensile strength for the sample used in the creep stiffness testing.Note that for the ParaLink products, the creep stiffness is presented in lb/rib and the MARVtensile strength, as provided by the manufacturer, is in lb/ft. Therefore for the ParaLink products,in order to obtain the minimum likely stiffness value for each product in consideration of theMARV tensile strength, TMARV found in Table 3-2 will need to be converted to lb/rib using thetypical rib spacing as provided in Table B-2 in Appendix B. Alternatively, the creep stiffness forthe ParaLink products can be converted to lb/ft using the same approach.

The regression for the accelerated creep tests (SIM) for the ParaWeb / ParaLinkproduct line produced log 3.25 and log 5.03, respectively, for the same %UTS. This was withinthe 90% confidence limits of log 2.52 to log 3.48 and log 4.04 to log 5.35 associated with those%UTS. This evaluation is summarized in Table F-14. Thus, the conventional and accelerateddata for the ParaWeb / ParaLink product line may be used together to construct the characteristiccreep rupture curve of the primary product.

“The National Transportation ProductEvaluation Program (NTPEP) wasestablished by the American Associationof State Highway and TransportationOfficials (AASHTO) in early 1994. Theprogram pools the professional andphysical resources of the AASHTOmember departments in order to testmaterials, products and devices ofcommon interest. The primary goals ofthe program are to provide cost-effectiveevaluations for the states by eliminatingduplication of routine testing by thestates; and to reduce duplication ofeffort by the manufacturers who produceand market commonly used proprietary,engineered products.” NTPEP

-- Rick Smutzer (IN), former NTPEP Chairman
