橡胶沥青同步碎石应力吸收层的设计研究

The Study on the Design of Synchronous Stress-absorbing Layer with Rubber Asphalt

针对橡胶沥青同步碎石应力吸收层的使用特性,在McLeod经验设计法的基础上,提出了以抗剪强度作为力学设计指标,并形成了橡胶沥青同步碎石应力吸收层的力学—经验设计法,同时给出设计示例;对采用两方法设计的应力吸收层进行了性能对比。研究结果表明:力学—经验法设计能设计出具有更高的抗剪强度、抗拉强度和动稳定度的同步碎石应力吸收层,值得推广应用。

On mechanistic-empirical design method,for the usage characteristics of synchronous stress- absorbing layer with rubber asphalt,the paper proposed anti-shear strength as mechanical design indicator.The research showed that the synchronous stress-absorbing layer not only improved the anti-shear strength, but also had the waterproof property and high-temperature performance.
