LOAD-ASSOCIATED CRACK MOVEMENT MECHANISMS IN ROADS

The increasing use of modified binders to inhibit reflection cracking, and the fact that these materials are sometimes unsuccessful, highlights the need to investigate the mechanisms of load-associated crack movement and crack reflection. The Crack-activity Meter (CAM), developed to measure load-associated crack movement, is discussed in this paper. Heavy Vehicle Simulator (HVS) tests, incorporating crack-movement measurements are discussed, as well as various types of crack-movement behavior. Four typical mechanisms of crack and joint movement are identified and discussed. This work has led to improved understanding of the mechanisms of crack movement and crack reflection and to a procedure, based on the measurement of crack movement, that can be used to aid rehabilitation design.
