旧水泥混凝土路面加铺沥青层关键技术研究

目前国内很多水泥混凝土路面正处于维修、待修状态。水泥路面加铺沥青层技术已成为旧水泥路面维修改造的主要方法之一。以水泥路面加铺沥青层技术为研究对象,对旧水泥混凝土板的处理、原材料的选择和反射裂缝的减少和延缓等关键技术进行研究,研究成果可以有效地指导水泥路面加铺沥青路面技术的应用,具有一定的工程实用价值。

Key Technology of Asphalt Overlay on Old Cement Concrete Pavement

Nowadays, many domestic cement concrete pavements are being maintained or waiting for maintenance. The asphalt overlay has become one of the main methods for the reconstruction and maintenance of old cement concrete pavement. Taking asphalt overlay on old cement concrete pavement technology as an object of study, key technologies such as the old asphalt pavement treatment, the selection of materials, the reducing and delaying of the reflective cracking are studied. The research results can guide the application of asphalt overlay technology effectively, and play an important role in the practical project.
