摘要
排水沥青面层因其足够的结构强度以及良好的表面特征和排水功能 ,与传统的密级配沥青混凝土路面相比 ,在路表防滑和保障行车安全方面具有很大的优势。通过室内试验及结合试验路段 。
With sufficient strength and excellent surface performance and drainage function, the porous asphalt facing is more advantageous when used for anti skid road surface and driving safety, compared with conventional dense graded asphalt pavements. Based on lab tests and trial road sections, the performance of the porous asphalt facing is studied and evaluated.
