橡胶改性沥青加铺应力吸收层技术研究

Examination of Techniques for Stress Absorpting Layer Paved with Powdery Rubber Modified Asphalt

半刚性材料的反射裂缝问题是不可避免的。采用橡胶粉改性沥青应力吸收层技术,能够很好地解决半刚性基层裂缝反射和雨水下渗的问题。从材料、施工和检测等方面对橡胶粉改性沥青应力吸收层技术进行了研究。

Reflection crack of semi - rigid materials is an unavoidable problem. Adopting the stress absorpting layer of powdery rubber modified asphalt is better able to solve the crack reflection and the rainfall infiltration of semirigid base. The paper examines above -mentioned techniques from materials ,construction and detection.
