Hamburg Wheel Tracking

According to the porous asphalt concrete’s big void structure as well as high temperature and rainy application environment, the author point out that using the conventional evaluation index such as high temperature stability and water stability to evaluate the PAC’s performance seem single, and then put up with estimating the PAC’s pavement performance by means of Hamburg Wheel Tracking under the water-high temperature’s comprehensive action. Studied on the PAC with the same raw materials and different gradations, and compared with the experimental results of AC-13 modified asphalt mixture and SMA-13, the results shows that, Hamburg Wheel Tracking test not only considered the water-high temperature’s comprehensive action on mixture, but also considered the mixture’s performance decay under long-term loading. Hamburg Wheel Tracking test can evaluate the PAC’s performance more practically, the PAC which materials and graduations reasonably designed have good performance, and its Hamburg Wheel Tracking final deformation is only 3.89mm, it can satisfy the demand from the high temperature and rainy environment. As well, the test results also comes to the conclusions that under the same materials and the same air voids, the PAC with coarse framework structure own better water stability and water-high temperature stability.
