Evaluation of Anti Reflective Cracking Performance of Warm Mix Recycled Asphalt Mortar Before and After Secondary Aging
In order to study the anti reflective cracking performance of warm mix recycled asphalt pavement,the in-fluence of Reclaimed Asphalt Pavement(RAP)content on the anti reflective cracking performance of warm mix re-cycled asphalt mortar after long-term aging was studied by combining Overlay Tester(OT)test with Digital Image Correlation(DIC)technology.The research results indicate that the RAP dosage has a significant impact on the anti reflective cracking performance of warm mixed recycled asphalt mortar after secondary aging.And the two are nega-tively correlated;Under the same aging conditions,the crack propagation law of recycled asphalt mortar with differ-ent RAP contents is basically the same.After secondary aging,the reflection crack of recycled asphalt mortar accel-erates in the initial cracking speed.
