SMA是近年来一种新型的沥青混合料结构形式。SMA路面在高温抗车辙、低温抗裂、抗水损害、抗老化与抗滑方面,均优于传统的沥青混凝土路面。它能显著地提高沥青混凝土路面的使用性能。该文介绍了盐城市解放南路改造工程的概况,并介绍了橡胶沥青灌缝、SMA面层施工过程及检测,以及SMA在城市道路改造中的应用。
SMA is a new type of asphalt mixture structure in recent years. SMA pavement is better than traditional asphalt concrete pavement in high temperature resistance to rutting, low temperature cracking resistance, water damage resistance, anti-aging and anti-slip properties. It can significantly improve the performance of asphalt pavement. This article introduces the general situation of the reconstruction project of the South Jiefang Road in Yancheng City and introduces the process of rubber asphalt filling joint, SMA surface course construction and testing, as well as the application of SMA in urban road reconstruction.
