Design and Comparative Analysis of Anti-skid Surface of HMA

Based on the recent study results,three kinds of anti-skid surfaces of HMA and the design method and technical criteria of mixture are adopted according to the features of test road.Then the changes of volumetric parameters under the condition of different gradations and asphalt contents of HMA and the performances of rut and water damage resistance of those anti-skid surfaces of HMA are compared and analyzed in detail.The test results indicate that the least variation of volumetric parameters with various gradations and asphalts contents is AC-13K and its performances improved to some degree extent.Finally the test road is paved using three kinds of anti-skid surface in the Luo-chang expressway.The study results provide reliable foundations to choose reasonable anti-skid surface.
