In order to design a anti-sliding and durable asphalt mixture, we independently develop two sets of laboratory equipment: the Laser Contour Detector of Asphalt Pavement and the Accelerated Rub Tester, with which we collect the plate surface contour every two hours for 5 times in the first 8 hours in the rub test, and then we make contour curves and analyze the angular distribution statistics of surface contour and thus we propose characterizing the skid resistance performance and durability of the asphalt pavement based on the maximum peak of angular distribution rate, which has been proved to be reasonable. By designing different gradations of SMA-13 and GAC-13 asphalt mixture and using the maximum peak of angular distribution rate to evaluate the skid resistance performance of different degrees of kneading, the asphalt mixture with better skid resistance has been made. That provides a reference for engineering application. The laboratory research develops a method for designing a anti-sliding and durable asphalt mixture based on the maximum peak of angular distribution rate, which makes up for the defects of the current stage where there is no ways to test the skid resistance performance and durability while designing the asphalt mixture.
