排水沥青路面的路用性能

排水沥青路面具有排水、防滑和降噪等功能，可提高行车安全性，降低交通事故率。为研究其路用性能，通过进行不同级配类型、不同沥青和相同级配类型、不同沥青的混合料路用性能的对比试验，结果表明，聚合物复合改性沥青的高低温性能及动力黏度优于高黏沥青A，排水沥青路面混合料路用性能优于开级配OGFC混合料的路用性能。

Road Performance of Drainage Asphalt Pavement

Drainage asphalt pavement has features such as drainage, anti-slip and noise reduction. It can greatly improve driving safety and reduce the incidence of traffic accidents. In order to study its road per-formance, contrast tests on road performance of mixtures with different types of gradation, different as-phalt as well as same gradation types, different asphalt are conducted. The result shows that polymer modi-fied asphalt has better high temperature performance and dynamic viscosity than asphalt A and drainage asphalt pavement has excellent road performance than OGFC asphalt mixture.
