我国在过去修建了大量的水泥混凝土路面,在经过过年运营之后病害严重影响到公路的使用状况。旧水泥混凝土路面改造有多重方式,而就地碎石化为最经济环保的再生工艺。本文通过理论计算和依托工程实施,验证和比较在采用柔性结构层,作为旧水泥混凝土路面再生加铺层的技术优势和经济效益,为新型加铺结构设计的推广提供素材。
In the past, a large number of cement concrete pavements were built in our country. After years of operation in the past years, the disease seriously affected the use of the roads. Old cement concrete pavement to transform a number of ways, and the local crushed into the most economical and environmentally friendly regeneration process. In this paper, theoretical calculation and relying on the implementation of the project, verify and compare the technical advantages and economic benefits of adopting the flexible structural layer as the regenerated overlay of the old cement concrete pavement, and provide material for the promotion of the new overlay structure design.
