Pioneers in Asphaltic & Unbound Materials Testing Established in 1990, Cooper Technology is a British company and the world leader in the design and manufacture of high performance testing equipment for asphaltic and unbound materials used in highway construction. The Nottingham Asphalt Tester (NAT), designed in the 1980’s by our Chairman Keith Cooper whilst at the University of Nottingham, was the first of its type. Since then our product range has increased steadily and now includes Gyratory Compactors and Roller Compactors to prepare and compact specimens in addition to Servo Hydraulic...

DESIGN, DEVELOP, AUTOMATE, TEST... Cooper Technology is much more than a manufacturer: all our machines are fully designed and developed by our dedicated in-house design team, all our engineers are degree educated in their relevant fields, and every engineering discipline is covered. Mechanical Design Via the use of 3D CAD packages we ensure our business is best positioned to utilise the most state of the art geometrical modeling systems available. These systems further permit calculating customer specific solutions within the shortest possible time. Electrical/Electronic Design The team...

Calibration Services from the Industry Specialist Prior to dispatch, where appropriate, each piece of our test equipment is calibrated by qualified engineers using procedures and equipment which are 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...

Cooper Technology’s business philosophy is to work closely with individual testing organisations to explore their needs and to find solutions to the challenges they face. Preventative maintenance is essential to ensure that key equipment operates day after day. It is imperative that this should be carried out by trained, experienced engineers and that OEM parts are used. Our customers stress that quality service and rapid response are essential factors considered when purchasing capital equipment. Cooper Premium Care has been developed as a customer-focused solution to mitigate the effect...

Servo-Pneumatic Universal Testing Machine CRT-UTM-NU Rapid determination of modulus, permanent deformation and fatigue of bituminous mixtures using cylindrical specimens that are cored from the highway or prepared in the laboratory

BRIEF INTRODUCTION 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...

Servo-Hydraulic Universal Testing Machine CRT-UTM-HYD A new generation of Universal Testing Machine combining state of the art technology with proven reliability and precision for research and standard testing

BRIEF INTRODUCTION The Servo-Hydraulic Universal Testing Machine (CRT-UTM-HYD) is a well designed, inexpensive machine specifically developed for the testing of materials used in pavement construction. A motorized, adjustable crosshead reduces the time between test setups. The programmable temperature cabinet provides the possibility to perform frequency/temperature sweeps. Accurate waveforms are digitally generated and applied by the actuator producing repeatable conditions that are simulative of those created by moving or static vehicles. The actuator is double-acting allowing both...
