水泥混凝土路面沥青加铺层反射裂缝防治

Prevention of Reflection Crack of Bituminous Paving Course on Cement Concrete Pavement

本文对水泥混凝土路面沥青加铺层反射裂缝形成机理进行了理论分析 ,采用弹性理论与有限元方法 ,对水泥混凝土路面上沥青加铺层应力和位移进行了计算 ,通过试验验证了理论分析与计算的正确性 ;针对反射裂缝形成机理 ,提出沥青加铺层反射裂缝的防治措施。

The paper analyzes in theory the formed mechanism of reflecting crack of bituminous paving course on cement concrete pavement. It also calculates the stress and displacement of bituminous paving course on the cement concrete pavement by elastic theory and finite element method. Through the test it tests and verifies the correctness of theory analysis and calculation. To counter the formed mechanism of reflecting crack, the paper puts forward the prevention measures for reflecting crack on the bituminous paving course.
