随着我国经济建设的迅速发展,公路运输事业得到蓬勃发展,同时由于高速、重载交通比重的增加,对高等级公路路面的使用性能提出了更高的要求。针对我国优质路用沥青的不足和水泥资源相对丰富,以及水泥混凝土路面研究取得了可喜的成果,有着比较完善的设计、施工技术规范的现状,将水泥混凝土路面应用于高等级公路是我国公路发展的一个策略。
With the rapid development of economic construction in our country, the highway transportation industry has been booming. Meanwhile, due to the increase of the proportion of high-speed and heavy-load traffic, higher requirements have been put on the service performance of high-grade highway pavement. In view of the shortage of high-quality asphalt in our country and the relative richness of cement resources, as well as the cement concrete pavement research has made gratifying achievements, with relatively perfect design and construction of the status of the technical specifications of the cement concrete pavement is applied to high-grade highway development in China A strategy.
