水泥混凝土路面沥青加铺层开裂防治技术研究

国内外的理论和实践表明，在原有路面上设置沥青混合料加铺层，可以有效地改善路表的使用性能和路面结构的承载能力。但加铺层在车辆荷载的不断作用下，仍会有不同程度的裂缝产生，从而影响道路的寿命和使用性能。因此。避免或减少沥青加铺层的裂缝就成为道路建设和养护工作者的重要任务。

Study on Crack Prevention of Bituminous Surface lies on Cement Concrete Roads

As foreign and domestic theory and practice shown, mixture layer of bituminous on pavement can improve the performance of pavement surface and carrying capacity of pavement structure. However, under the continual action of vehicles, there will be cracks occurring in bituminous layer, and affects the using life and capacity of the road accordingly. Therefore, it is an important task for road construction and maintenance to avoid or reduce cracks in bituminous layers.
