摘要
防治反射裂缝,使现有道路能够继续承担未来的交通荷载是旧混凝土路面加铺沥青混凝土需要解决的主要问题.橡胶沥青应力吸收层具有吸收应力、减少反射裂缝、防水、粘接力强等优点.通过工程实例,对沥青加铺层反射裂缝产生机理、加铺层设计方法以及基于应力吸收层的沥青加铺层结构及材料等作一些探讨;重点论述橡胶沥青应力吸收层的作用机理和相关的施工工艺.
Prevention of reflection cracks and making the existing roads to continuously undertake the future traffic load are the main problems that need to solve for the old concrete pavement with asphalt concrete. Rubber asphalt stress absorbing layer has the advantage of stress absorption, reducing the reflection crack, waterproof, strong adhesion and so on. According to the engineering example, we can made a few discuss about the reflection crack in asphalt overlay mechanism, overlay design method and asphalt overlay structure and materials based on stress absorption layer and so on. The rubber asphalt stress absorbing layer mechanism and related construction technology are discussed.
