Overlay Tester, 240V 50/60Hz

Supports the following standards: Tex-248-F, ASTM WK26816

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 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 Cox/Cooper Texas Overlay Tester it is possible to characterize both the crack initiation and crack propagation properties of asphalt mixtures. Cox/Cooper have developed the Texas Overlay Tester, which is a dedicated, state-of-the art piece of equipment for carrying out this test.

Automatically calculates critical fracture energy and crack resistance index according to Tex-248-F.
