旧水泥混凝土路面上沥青路面罩面实用设计方法的研究

Research on the Practical Design Method of Asphalt Pavement Overlay on Existing Cement Concrete Pavement

针对旧水泥混凝土路面沥青路面罩面结构特点,提出以控制罩面层产生反射开裂及罩面层与旧水泥混凝土界面产生剪切破坏为标准的沥青路面罩面厚度设计方法,并分析了相应应力计算公式的合理性。

In this paper,a thickness design method of asphalt pavement overlay is discussed in accordance with the structural properties of asphalt pavement overlay on the existing cement concrete pavement.The method established criteria by controlling the reflection cracking of the overlay and shear failure between the overlay and the existing cement pavement.Furthermore,the corresponding stress formulas are analyzed.
