摘　　要：在McLeod经验设计法基础上,提出了以层间抗剪强度为设计指标的力学-经验设计法,并对不同方法设计得到的同步碎石封层材料的性能进行了对比研究。研究结果表明:力学-经验法设计的同步碎石封层材料具有很高的抗剪强度、抗拉强度和动稳定度。Taken anti-shear strength as the design indicator,a mechanistic-empirical design method of synchronous seal coat with rubber asphalt was brought forward based on McLeod empirical design method.Moreover, the performance of synchronous seal coats designed by the two different methods were compared.The results show that the synchronous seal coat designed by mechanistic-empirical method has higher anti-shear strength,tensile strength and dynamic stability.
