微表处技术对沥青混合料性能的改良研究

his paper study the extent and factors of asphalt concrete pavement damage on the different soaking status by asphalt surfacing technology，By Marshall stability and weight loss rate of comparative test and analysis of common asphalt concrete materials and micro surfacing materials in different conditions of water damage resistance and damage form of asphalt concrete. Experiment shows that asphalt surfacing technology can effectively reduce the water damage of asphalt concrete pavement. The stability of wet and dry cycle condition is best, and the effect of improving the stability of water is the worst.
