April 14, 2014 MEMORANDUM TO: Scott Alexander, PE

Project Manager FROM: Chaz Weaver, PE, MEM District Materials Engineer SUBJECT: Design Changes at PAC Review The intent of this memorandum is to document the design changes required by Staunton Materials Section, in contrast to those proposed by GeoConcepts in their Final Soil Survey Report of July 26, 2013. Several plan sheets provided for the Pre-Advertisement Conference (PAC) included proposed pavement structures and asphalt pavement mixes not in concurrence with the current Materials Division Manual of Instructions. The report noted above is the third version of such, and it was determined not in the best interests of the Department nor the project schedule to continue redacting this report for the many and various errors and omissions contained therein. Staunton Materials Section’s plan review comments for the PAC meeting included, but were not limited to (see attached combined review comments):

1. Changing the temporary pavement design to eliminate expensive surface asphalt mix. The comment requested SM-12.5A be changed to less expensive IM-19.0A. (Comment #9)

2. Using current version of Note G-6 (provided). GeoConcepts will review their pavement design and slope stability analyses to determine the minimum required CBR value. They will also determine and list areas where unsuitable material is expected. Project soils are acceptable as stormwater management basin embankment material, which should be noted. (Comment #160)

3. Adding binder type to SMA asphalt mixes. The consultant omitted “(70-22)” after “SMA-12.5” and “SMA-19.0” – which would have led to issues during bidding and construction. (Comment #168)

4. Change Inset E to Superpave asphalt mixes in lieu of SMA. Crossovers do not require these expensive mix types. (Comment #170)

5. Changing full-depth reconstruction of sections of US 11 and US 37 to full-depth widening and mill/replace or overlay. Northwest Regional Operations requested this change to eliminate critical maintenance of traffic issues, to which Staunton Materials Section agrees. (Comment #173)

6. Changing Ramp E to Ramps F and G pavement designs for consistency. This pavement structure (Inset C) is sufficient for Ramp E also, and this change will simplify both the plan sheet and construction operations. (Comment #178)

7. Deleting extraneous materials in entrance details. Aggregate No. 21A and SM-9.5D aren’t used anywhere else on the project. A “D” mix is not suitable for entrances. (Comment #179)

8. Adding subgrade stabilization geotextile under Tasker Road and Hillandale Lane pavement structures. Due to highly plastic subgrade soils and relatively thin pavement structures, geotextile was required to limit contamination of the aggregate subbase. (Comment #180)

9. Adding geotextile under asphalt path. Discussed during the meeting, geotextile directly below asphalt will reduce edge cracking. (Comment #181)

10. Adding leveling course and using SM-9.5AL. Staunton Materials Section agrees with Construction’s request for additional asphalt quantities to allow a leveling course where needed to provide smooth transitions – this will improve the overall rideability and aesthetics of the project. An “L” (limestone) mix may be used to reduce costs, as this layer will not be subjected to long-term traffic. (Comment #189)

11. Reviewing stormwater management basin slope design(s). Staunton Hydraulics will determine whether impounding water with a roadway embankment is allowable. GeoConcepts will further analyze the Ramp D embankment as a critical slope, per Materials Division Manual of Instructions (not provided in Final Soil Survey Report). (Comment #200)

12. Adding concrete cradle to double 48” pipes on Sheet 2H(14). Despite the consultant’s objections, this basin will be subjected to several drawdown events, and should be designed accordingly. (Comment #209)

13. Reviewing expected settlement under box culverts on Sheets 2M(2) and 2M(4). GeoConcepts did not provide any calculations, discussion or recommendations regarding structures under these relatively large fills. (Comment #230)

14. Correcting undercut locations and/or depths shown in cross-section sheets. Consultant will correct undercut shown to reflect GeoConcepts’ intent in the Final Soil Survey Report. Subgrade undercut is not necessary (or desired) as select material will be used.

The remainder of Staunton Materials Section’s comments were semantic, cosmetic or minor in nature and should not require sign and seal; however, all comments are attached. If you have any questions or concerns, please let me know.

There was no analysis performed at the stop controlled RT

37 WB to RT 11 NB “slip ramp”. During Phases 1C and 1E,

RT 11 NB is reduced to one lane at its intersection with the

slip ramp. This constriction will reduce the number of

available gaps for right turning vehicles off the slip ramp.

There is the potential for slip ramp backups to extend all the

way back to RT 37. This analysis needs to be performed,

at least for Phases 1C and 1E.

Phases 2 and 3 reduce the RT 37 EB and WB movements

across I-81 to one lane each. All approaches will be

significantly over capacity in the AM and PM peak periods

(and probably throughout the day as well). All stakeholders

need to be aware that these reductions will create massive

delays. Reducing the EB LT movement onto I-81 NB to a This suggestion will be considered and

discussed with VDOT.single thru-left lane in particular will cause delays. One

suggestion is to route RT 37 EB -> I-81 NB left turn vehicles

thru the I-81 NB Ramp signal in the EB direction, U-turn at

Relocated Tasker Road and turn right onto I-81 NB. This

will require additional detour plans to be in place.

During Phases 2-5, there is at least one I-81 Off-Ramp with

a LOS F in the AM or PM peak. A LOS F indicated the

movement is over capacity and in effect, will have an

infinitely increasing queue. If that is the case, it will be near

impossible to prevent queues from reaching the interstate.

The TMP does not provide any mitigation measures to

prevent that. This needs to be changed. The TMP and the

TTC Plans must incorporate very specific requirements on

what to do if queues start get close to the interstate on

either of the ramps. This is a major safety concern.

Preventing traffic from queuing back onto the interstate is


Preventing traffic from queuing back onto the interstate is

important for NWRO to address and alleviate under normal

traffic operational conditions. We expect the contractor to

do the same during construction. The contractor shall be

responsible to not allow this to happen and shall provide

plans to prevent this from happening. These requirements

need to be incorporated into the contract documents and

construction plans.


The TMP did not analyze vehicle queuing during any

construction phase. This needs to be done to identify and

mitigate the effects of queue spillback, inadequate turn lane

storage, and most importantly queuing on the I-81 off ramps storage, and most importantly queuing on the I-81 off ramps

reaching the interstate.


The Contractor needs to submit copies of all the Synchro

files used in the TMP. This is necessary for review and will

be a valuable tool for VDOT during construction.

Tasker Road design speed is shown as 40 MPH with a

posted speed limit of 35. Existing speed limit is posted as

45 MPH. A speed study will need to be completed to justify

this reduction.

Recommend a 1 year establishment period to avoid

unnecessary administrative cost and burden to the

390 X149-156 MaterialsPer final soil survey report, this 4:1 slope could be steeper

(and reduce right-of-way costs).

4:1 slope is used under Future Route 37

extension from sta. 39+00 to 42+50 and

is already within proposed right of way.

2:1 slope could be used from sta. 42+50

(X154) to 45+00 (X156) to reduce

proposed temporary construction

easement for slopes. Note: The right of

way is proffered land from the
