Corporate Social ResponsibilityOrganisations, like individuals, depend for their survival, sustenance and growth on the support and goodwill of the communities of which they are an integral part, and must pay back this generosity in every way they canWe strongly believe that our primary obligation or duty as corporate entity is to our stakeholders we are just as mindful of the fact that this imperative does not exist in isolation; it is part of a much larger compact which we have with our entire body of stakeholders- from employees, customers, business partners, eco-system, local communities, and to society at large.For us, being socially responsible is not an occasional act of charity or that one-time token financial contribution to the local school, hospital or environmental NGO. It is an ongoing year-round commitment, which is integrated into the very core of our business objectives and strategy.Because we believe that there is no contradiction between doing well and doing right. Indeed, doing right is a necessary condition for doing well.
Cooper engages with Colts to Africato help underpriviliged childrenMANUFACTURE ECO-FRIENDLY EQUIPMENT
Although it is very challenging to manufacture eco-friendly testing equipment for asphaltic and unbound materials, however our engineers endeavour to work on more energy efficient designs and manufacture energy efficient testing equipment.As part of our overall commitment to corporate social responsibility, Cooper Technology developed its first eco-friendly testing equipment called Auto Lift Arm ECO Wheel Tracker in 2010. It is small and compact machine for maximum energy efficiency.
AUTO LIFT ARM ECO WHEEL TRACKER IS 28% MORE ENERGY EFFICIENT THAN ITS PEER WHEEL TRACKING MACHINES.
RESPECT FOR ENVIRONMENT
We understand the importance of environment. At Cooper Technology we try to minimise waste and take every single and even simple steps like switching off the lights and equipment when not needed, switching off computer monitors during the night, avoid printing unnecessary emails and recycling paper. We have cut-down hardcopy catalogue printing by 85% and prefer to promote our product digitally.
Remote Support ServiceCooper Technology provides an easy access, cost effective remote service support program that allows us to fix many issues on your computer, and Cooper testing equipment, from the comfort of your laboratory or business. All you need to do is download our custom remote support program and we will do the rest. Once work is completed all traces of the program are removed and we are unable to access your computer again until you initiate the connection. All connections from our office to your system are encrypted so you can rest easily knowing that your information is completely safe.
We can fix a large range of problems remotely including, but not limited to:
Software problemsInstallation of programsSoftware patchesSoftware upgradesMaintenanceProgram configurationTests and PC optimisation
This is just a small list of what can be accomplished remotely and, best of all, you dont even have to be at the system once you run the program.
Calibration ServicesBritish scientist Lord Kelvin is quoted from his lecture to the Institution of Civil Engineers, 3 May 1883 as saying:
I often say that if you can measure what you are speaking about and express it in numbers you know something about it; but when you cannot express it in numbers your knowledge is a meagre and unsatisfactory kind; it may be the beginning of knowledge but you have
scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be.
This famous quote emphasises the importance that measurement has in science, industry and commerce. Prior to dispatch, where appropriate, each piece of our test equipment is calibrated by qualified engineers using procedures and equipment which is scrutinised annually by the United Kingdom Accreditation Service (UKAS). The International Laboratory Cooperation (ILAC) links UKAS with accreditation bodies worldwide. All equipment needs to be UKAS calibrated and traceable to national standards in order to satisfy typed testing as described in the EN13108. Although equipment from Cooper Technology normally continues to perform correctly and produce accurate results for many years, over time and through application there could be some component wear and the output from electronic components may drift. A highways material laboratory is not an ideal environment for instruments that must, in some cases, measure displacements within accuracies in excess of one millionth of a metre.
The Benefits of CalibrationTo comply with your internal quality assurance policy and to demonstrate a disciplined commitment to sound laboratory management.
To have the confidence that your test equipment continues to function correctly and to ensure that it maintains the required level of measurement accuracy you would expect.
To enhance your customers confidence in a reliable and accurate testing service.
To gain national and international recognition of your testing and to help you to access foreign markets where laboratory accreditation is
compulsory.
The equipment needs checking and calibrating at least annually by one of our fully trained, UKAS approved engineers from Cooper Technology Calibration Division. On completion of the calibration, our engineer will provide you with an update on the condition of the equipment, together with a traceable calibration certificate.

I would like to comment on how impressed we are with the new Wheel Tracker ECO Small Device since we purchased the machine beginning this year. It has been in constant use. The benefit that we have seen in that this version is fully automated from start to finish, compared to the standard 1 arm wheel tracker, which is quite a bit labour intensive where you have to physically place the arm/wheel on the specimen, wait until test temp is achieved before starting the test, and lifting the wheel off the specimen at the end of the test. Our technicians also find our software a lot more user friendly.

CRT-UTM-NU Servo-Pneumatic Universal Testing Machine
KEY FEATURES
DESCRIPTION
This machine is a development of the NAT which was developed by Keith Cooper and Professor Steven Brown at the University of Nottingham. The use of a high precision servo-pneumatic valve in conjunction with a low-friction actuator and sophisticated data acquisition and control, results in a performance that is equal to many servo-hydraulic systems.
Accurate, digitally generated waveforms are applied by the actuator producing repeatable stress variations in test specimens that are simulative of those in a road pavement due to moving traffic. The actuator is double-acting allowing both compressive and tensile forces to be applied. A triaxial cell system is available for the measurement of the resilient modulus of unbound materials.
Low cost dynamic loading universal test system ideally suited to testing asphalt and unbound granular materials

CRT-PUMA Precision Unbound Material Analyser(PUMA)
DESCRIPTION
The Precision Unbound Material Analyser (PUMA) is a new type of laboratory test equipment designed to fill the gap between expensive and complex laboratory tools (such as triaxial cells) and more empirical methods (such as the California Bearing Ratio test). It is designed to generate realistic values of modulus for use in road pavement design.The PUMA can be used to test unbound, hydraulically bound and asphaltic materials. It has been designed as a low cost, easy to use and practical tool, but one which is capable of generating scientifically meaningful data (Modulus and Resistance to Permanent Deformation), for use in road pavement design. It can be used to test specimens made from granular material, soil or lightly stabilized material etc, with a maximum particle size of 31.5mm. The PUMA is proposed as a direct equivalent to the Springbox, with the advantage that initial stress conditions can be accurately controlled. It is a simple test, suited to generic specification, that holds the promise of increased confidence in pavement foundation design, particularly in cases where favourable weather conditions during construction result in unrepresentatively high Dynamic Plate Test (DPT) values, or in cases where stabilised soils or cold-mix asphalt are employed.

DESCRIPTION
The Saturated Aging Tensile Stiffness (SATS) test was developed by Professor Andrew Collop and co-workers of University of Nottingham. The test is a combined ageing/ moisture sensitivity test to evaluate the performance of macadam coated binder course and base mixtures.The test involves the positioning of core samples in a high ressure (21 bar air) and high temperature (85C) environment for 4 days to prematurely age the sample. These samples are then tested in the Nottingham Asphalt Tester/ NU14 to measure the tensile strength of the core samples.This test has been adopted by the UK Highways Agency as a compulsory QC test method for any asphalt that is supplied to them. This requirement came into force in autumn 2007.Due to the high pressures that are used in this test, the equipment must be constructed in a suitable fashion. This equipment is used by a number of leading asphalt suppliers in the UK.

CRT-TOT Texas Overlay Tester
DESCRIPTION
ASTM WK26816 (Proposed draft); TEX-248-F
DESIGN AND TESTING OF BITIMINOUS MIXTURES01
In recent years many mixture design methods have produced materials that are stiffer, leaner and more resistant to rutting, however, such materials are often more susceptible to fatigue and reflection cracking. The Texas Overlay Tester (CRT-TOT) was designed to simulate the expansion and contraction movements that occur in the vicinity of joints or cracks and which result in reflection cracking in overlays. With the CRT-TOT it is possible to characterise both the crack initiation and crack propagation properties of asphalt mixtures.
Cooper Technology has developed the CRT-TOT, which is a dedicated, state-of-the-art piece of equipment for carrying out this test.Increasing bitumen content will significantly improve the reflective cracking resistance of asphalt mixtures and materials with low resistance can fail in minutes. TOT results have correlated well with field performance and have shown good correlation with both beam fatigue test results and the low temperature performance of asphalt mixtures in the field. The test is rapid and has been shown to be repeatable. The TOT is performed on standard size samples, typically 6 inch (150 mm) long by 3 inch (75 mm) wide by 0.5 to 1.5 inch (12mm to 38 mm) high. These specimens can be cut from field cores or from laboratory compacted specimens, which can be prepared with the Cooper Gyratory Compactor (CRT-GYR).
The specimen is precisely positioned and glued to two base plates using the gluing frame (CRT-TOT-GLUE). This glued assembly is put into the machine using the zero stress carrying frame. Sample dimension and test conditions are entered through the surface mounted Cooper TOUCH+ touch-screen panel. A test can be instantly started by the user, or will commence after a target test temperature has been reached.

A triangular waveform in constant deformation mode is applied, alternately extending and compressing the specimen so as to simulate the movement of the cracked, rigid material under the overlay. The test will automatically stop when the test end conditions have been met. It is suggested that the TOT could complement mixture design methods where the emphasis is mainly on resistance to rutting thus ensuring that mixtures are not too lean and prone to cracking. It will also provide the means of assessing different binders and binder modifiers.
A proposed new ASTM International standard for Determining the Susceptibility of Bituminous Mixtures to Reflective Cracking using the Texas Overlay Tester is currently under development. It is hoped that this International standard will improve the test method by providing a unified sample preparation procedure as well as overall improved precision. The CRT-TOT will, of course, meet any changes prescribed in this new standard.

DESIGN AND TESTING OF BITIMINOUS MIXTURES01
The OEM-Cooper Thermal Stress Restrained Specimen Test (TSRST) is used to determine the low temperature cracking susceptibility of asphalt concrete. In the early 1990s the TSRST was developed by OEM with Oregon State University (OSU) as part of the Strategic Highway Research Program in the USA. The test method became AASHTO TP10. This method has now been updated and there is a proposed newAASHTO standard - Determining Thermal Cracking Properties of Asphalt Mixtures through Measurement of Thermally Induced Stress & Strain.
The TSRST test has also been included as one of the tests within EN12697-46. OEM-Cooper have developed the TSRST device to perform tests included in this standard. Now as a multipurpose low temperature testing machine the TSRST has been renamed the Asphalt Pavement Thermal Testing System (APTTS).
With over 20 years of experience, and as the original developers of the TSRST OEM-Cooper are the recognised word experts in the field.

EN 12697-24 Annex A; EN 12697-26 Annex A; NF-P98-260-2
DESIGN AND TESTING OF BITIMINOUS MIXTURES01
The two-point bending test on trapezoidal specimens is, arguably, the most repeatable and reproducible bending test method detailed in the relevant EN12697 standards. In this test the specimen is mounted as a vertical cantilever. The base is fixed and the top is moved sinusoidally with a constant displacement amplitude. The trapezoidal shape ensures that the maximum values of bending stress and strain occur away from the ends of the specimen where there are likely to be stress concentrations. With the Cooper Technology equipment, two or four trapezoidal specimens are tested simultaneously and stiffness modulus can be determined at a range of frequencies and temperatures. In the fatigue test the specimens are subjected to a constant strain amplitude at a selected frequency and temperature until the stiffness modulus decreases to a user-selected target level (normally 50 percent of its initial value).

DESCRIPTION
Wheel tracking is used to assess the resistance to rutting of asphaltic materials under conditions which simulate the effect of traffic. In this machine, two 500 x 180mm specimens are tested simultaneously by tracking with wheels fitted with pneumatic tyres under specified conditions of load, speed and temperature while the development of the rut profile is monitored at specified intervals during the test. The moulded specimens are inserted and removed from the Wheel Tracker using an Easy-load system. A unique instrumented measurement device, linked to the data acquisition, is used to measure the development of rutting during testing. The test procedure and conditions are controlled and data acquired using Windows software running on a host computer via a high speed digital interface and signal conditioning system.

The Hamburg type dual arm immersion Wheel Tracker is widely used to evaluate the resistance to rutting and moisture susceptibility of asphalt mixtures following either EN12697-22 or AASHTO-T324.
The device was developed in the 1970s by Esso A.G. of Hamburg, Germany. It was based on the TRL wheel tracker which is also now included in EN12697-22. Originally the Hamburg test was used by the City of Hamburg to measure rutting susceptibility. The test was performed for 9,540 wheel passes at either 40 or 50C. Water was used to obtain the required test temperature rather than air. The City of Hamburg later increased the number of wheel passes to 19,200 and found that some mixtures began to deteriorate from moisture damage. Greater than 10,000 wheel passes was generally needed to show the effects of moisture damage.
Specimens can be prepared in the laboratory, or cores taken from the road can be used. Loaded steel or rubber wheels track a sample under regulated load, speed and temperature, whilst the development of the rut is constantly monitored and recorded throughout the test.

Data is recorded throughout the test and can be exported to PC via a data stick for further analysis
Studded tyres greatly reduce skidding and accidents on snow or ice covered roads. However, all too often the studs come into contact with the road surface. The use of studded tyres is very costly in terms of annual load wear. Additionally, as the studded tyres wear the pavement they eventually cut ruts in the road that can fill with water to create a hydroplaning hazard in wet weather. A further issue is the polluting dust that is created. The Prall Test (Method A) has proved to be the most successful way to investigate abrasion due to studded tyres. At the same time reproducibility has been an issue. At Cooper we have assessed the aspects of the test crucial to performance and improved them, via the fitment of a second test chamber, thus significantly reducing variability.
The CRT-PRALL is designed to carry out the Prall Test according to EN12697-16 Method A in which a cylindrical specimen of asphalt having a diameter of 100mm and a length of 30mm is tested at a temperature of 5C. The specimen is worn by abrasive action over a standard time period of 15 minutes by 40 steel spheres. The loss of volume in millilitres is recorded and reported as the abrasion value.

PRODUCT CODE
CRT-GYR Gyratory Compactor
Gyratory compaction is considered to be one of the best methods of laboratory compaction for the assessment of compactibility and the manufacture of test specimens.Compaction is achieved by the application of a vertical stress (normally 600KPa) via end platens to a known mass of asphaltic mixture within a 100 or 150mm internal mould. The longitudinal axis of the mould is rotated (gyrated) at a fixed angle to the vertical whilst the platens are kept parallel and horizontal.
During compaction the height of the sample is automatically measured and both the mixture density and void content calculated. The compaction data is shown on-screen in graphical and tabular format as compaction progresses and it is also saved in Microsoft Excel compatible format. The operator can choose whether to compact for a certain number of gyrations or until a target mixture density or void content is achieved.
Problems with existing compactors are mainly related to build quality and ease of use. Unlike most compactors 100 and 150mm moulds can be tested without changing machine parts. A filled Gyratory Compactor mould is heavy and often very hot.
In many cases these moulds have to be lifted in and out of Gyratory Compactors. With the CRT-GYR no lifting of filled moulds is required. They are automatically lowered into position for compaction and then lifted up again for transfer to the integrated demoulding system.
