半柔性复合路面结构设计理论和设计方法

半柔性路面是一种在开级配沥青混合料中填充水泥胶浆而形成的兼具沥青路面与水泥混凝土路面特点的复合路面。通过对半柔性复合路面破坏状态调查,提出了相应的设计标准。结合半柔性复合路面材料的抗压模量、劈裂强度、应力应变关系曲线及其结构的荷载响应特点,提出了该路面结构的设计理论及设计方法。

Study on Design Theory & Method of Semi-flexible Compound Pavement Structure

Semi-flexible pavement is generally described as an open-graded asphalt concrete mixture, which is filled with Portland cement grout. The paper analyzed the damage state of semi-flexible compound pavement, and then put forward the corresponding design standards, combined with semi-flexible pavement material composite compressive modulus, splitting strength, stress-strain curve and its structure in response to the load characteristics, put forward design theory and design method of the new type of pavement structure.
