摘要
Abstract
Taking a municipal road in Beijing as an example,PA-13 asphalt mixture gradation design was carried out by using composite modified asphalt with high viscosity,and the key technology of construction of asphalt pavement with large void ratio was defined.The drainage performance and compaction degree of pavement were tested and analyzed after construction.The results show that the maximum water seepage coefficient of the pavement can reach 7 623 mL/min,and the drainage effect of the drainage asphalt pavement is large,which is significantly higher than the standard value of 4 500 mL/min,and the influence of road water on driving safety can be effectively reduced.In addition,the compaction degree of the pavement can reach 98.8%,which ensures the stability of the asphalt pavement with large void ratio.关键词
