Abstract
In order to study the application effect of high-viscosity modified SMA-13 asphalt mixture in municipal road engineering,taking a new municipal road inPutian City,Fujian province as an example,the optimal asphalt ratio of the mixture was determined by optimizing the pavement mix ratio design,and the road performance of the asphalt pavement after paving was tested.The results show that the dynamic stabili-ty of high viscosity modified asphalt SMA-13 asphalt mixture at 70℃can reach 8 625 times/mm.The structural depth,compaction degree and flatness of the left and right width of the asphalt pavement can meet the requirements of the code,and the construction process is accurate,and the overall performance of the pavement technology is excellent,which shows a broad application prospect in the municipal road engineer-ing.关键词
