水泥混凝土路面沥青加铺技术研究

Research on Asphalt Overlay Technology for Cement Concrete Pavement

随着国内车流量的不断增加,许多水泥路面还未达到使用寿命就已出现各种路面病害,沥青加铺技术的出现可以让这些破损的水泥路面得以继续使用。论文从原路面的检测与评价、新路面的结构与材料设计方面更深入研究沥青加铺技术,试验发现:以4 cmSMA-13、6 cmAC-20复合结构加铺的路面具有优异的路用性能。

With the increasing traffic flow in China,many cement pavements have appeared various pavement diseases before reaching the service life.The emergence of asphalt overlay technology can make these damaged cement pavement can continue to use.In this paper,the asphalt overlay technology is further studied from the detection and evaluation of the original pavement and the structure and material design of the new pavement.The test shows that the pavement with 4CMSMA-13 and 6CMAC-20 composite structure has excellent pavement performance.
