Abstract: Reflective cracking is the main distress of asphalt overlay over existing pavements. This paper briefly discusses the mechanisms of reflective cracking, and describes the concept of overlay tester and the upgraded Texas Transportation Institute (TTI) overlay tester.
Finally, three case studies are presented to validate the upgraded TTI overlay tester. The results clearly show that the upgraded TTI overlay tester can effectively differentiate between the reflective cracking resistance of different asphalt mixtures. It is also found that the reflective cracking resistance of asphalt mixture has a good correlation with the asphalt binder used. Stiff binder has poorer reflective cracking resistance than soft binder.
