摘　　要：国内外旧水泥混凝土路面改造工程较多采用沥青加铺层,但如何控制反射裂缝产生的时间和扩展的速度至今仍是一个路面工程难题.分析沥青加铺层防止反射裂缝的措施的目的是控制开裂,而不是消除开裂,讨论构建应力吸收层对于沥青加铺层的使用性能和使用寿命起着决定性作用.Asphalt-covered layers are applied to the old cement concrete pavement reconstruction domestically and overseas. However,there exist the problems of how to control the time of reflectiion crack＇ s occurrence and crack expansion rate. It is analyzed that asphalt covered layers to prevent reflection crack are to control crack instead of eliminating it, and it is discussed building up stress adsorbed course play a decisive role in the operation property and operation life of the asphalt-covered layers.
