摘要
该文对贝雷法提出的级配参数进行了分析,设计试验方案,选用单轴贯入试验测试沥青混合料抗剪强度,结果分析发现,级配参数CA比和最大公称粒径对沥青混合料抗剪强度有显著影响,对考虑抗剪性能的级配优化有一定的实际意义。
The article analyzes the gradation parameters developed in Bailey method. In the design experiment scheme, the uniaxial penetration test is used to test the shear strength of the asphalt mixture. The result shows that CA ratio of gradation parameter and the maximum nominal size evidently influence the shear strength of asphalt mixture. It has the practical merits for considering the gradation optimization of the shear resistant performance.
