摘要
针对橡胶沥青与常规沥青材料的微观结构及力学性能差异,选用国内外在橡胶沥青混合料中使用较多的AR-AC-13矿质级配,选取实际路面常见的3种空隙率,依据正交试验思路安排试验,采用冻融劈裂强度比评价混合料的水稳定性。通过对3种空隙率橡胶沥青混合料冻融强度比的对比分析,探讨了空隙率对橡胶沥青混合料水稳定性的影响。
According to the differences in microstructure between conventional asphalt and rubber asphalt material, AR-AC-13 mineral graduation method widely used in the rubber asphalt mixture at home and abroad was chosen, three common air void was used to arrange test, and freeze-thaw splitting strength ratio was adopted to evaluate water stability of the mixture. Through comparatively analyzing freeze-thaw splitting strength ratio of three air void rubber asphalt mixture, the influence of air void on water stability performance of asphalt mixtures was studied.
