Abstract: For the high temperature, rainy and heavy traffic region in Chongqing, improving the resistance to rutting and water damage of asphalt pavement was very important. In view of this,the research about the pavement performance of lake asphalt modified asphalt mixture,and NS-lake asphalt compound modified technology were studied. Firstly,the addition of lake asphalt can improve pavement performance far more than common mixture,especially the high temperature performance,but the effect is low compared with SBS modified mixture. Secondly,NS and lake asphalt compound modified can significantly improve the pavement performance,with better effects than lake asphalt modified single or SBS.
