Abstract

In order to study the reflection crack resistance of asphalt mixture, using Overlay tester, crack resistance property of five asphalt mixture types were analyzed based on the grey relation analysis. The paper analysis the influence of mixture types temperature and volume index (void ratio) on the anti-cracking performance. Result shows that grey relation entropy analysis is more scientific than grey relation. The dense-graded HMA(AC-13 CAM SMA -13and Super pave-13) generally exhibited good cracking resistance than open-graded HMA(OGFC-13). For the HMA mixes evaluated based on the Overlay tester. The higher the temperature, the better the crack resistance of asphalt mixture .No distinctive relationship appeared to exist between the peak load and OT cycles. This indicated that OT cycles was not necessarily dependent on the peak load. Similarly, the magnitude of the peak load could not be used as an indicator of the HMA mix cracking resistance.
