透水沥青路面技术在水泥混凝土路面改造中的应用

水泥混凝土路面是指以水泥混凝土为主要材料做面层的路面,俗称白色路面,它具有强度高、稳定性好、使用年限长、养护维修费用少等优点。但在交通荷载及环境等因素影响下,水泥混凝土路面使用一段时间后,会出现板块开裂、角隅破碎、错台等不同程度的病害,为了恢复旧路面的使用性能,往往采取加铺沥青混凝土面层的措施。该文结合上海市奉贤区环城东路水泥混凝土路面改造为透水沥青路面的工程实例,介绍了透水沥青路面,以及橡胶沥青应力吸收层技术的应用。

Application of Porous Asphalt Pavement Technology in Reconstruction of Cement Concrete Pavement

The cement concrete pavement is a pavement with the surface made of the cement concrete as the main material, commonly called the white pavement. It has the advantages of high strength, good stability, long service life and low maintenance cost. However, the different faults of sectional cracking, corner breakup, split level and etc. will appear on the cement concrete pavement after a period of use under the factors of traffic load and environment. In order to recover the use performance of the old pavement, the measures are often taken to repave the asphalt concrete surface. As an example of reconstructing the cement concrete pavement into the porous asphalt pavement for Huancheng Road (E) in Fengxian of Shanghai, the article introduces the application of porous asphalt pavement and the rubber asphalt stress absorption layer technology.
