摘　　要：采用基于路用性能的贝雷法级配理论进行应力吸收层级配设计,建立了CA值与动稳定度、低温弯曲、水稳定性能、抗剪切性能的关系。试验结果表明:当应力吸收层级配的CA值为0.35~0.44时各性能指标均最优,并提出了应力吸收层的集料级配范围。The grading design of stress absorbing layer is carried out by using the grading theory of Bailey method based on road performance.The relationship among CA value and dynamic stability,low temperature bending,water stability and shear resistance performance is established.The test results show that when CA value of the grading of stress absorbing layer is 0.35~0.44,all performance indexes are optimal and the aggregate grading range of stress absorbing layer is proposed.
