摘要
环氧沥青混凝土是一种超高级路面材料,其主要性能受空隙率影响比较大。对环氧沥青混凝土空隙率与环氧沥青混凝土水稳定性、弯曲性能和疲劳寿命间关系展开室内研究。试验结果表明:随着环氧沥青混凝土的空隙率增大,环氧沥青混凝土冻融劈裂强度降低,冻融劈裂强度比减小,环氧沥青混凝土抗水损坏性能降低;随着空隙率增大,环氧沥青混凝土低温弯曲性能降低,疲劳寿命减少,抗疲劳性能降低。严格控制环氧沥青混凝土的空隙率对提高环氧沥青铺装的性能具有重要作用。
The epoxy asphalt concrete is a kind of super senior pavement materials,the main performance of which depends on the porosity.Based on laboratory tests,the relationships between porosity and water stability,flexural and fatigue performance of epoxy asphalt concrete were studied.The research results showed that the porosity influenced epoxy asphalt concrete performance.With the increase of porosity,the freezethaw splitting strength（ratio）,the anti -moisture behavior,the fatigue life and the anti -fatigue behavior of epoxy asphalt concrete all decreased.Controlling porosity of epoxy asphalt concrete stricdy played an important role on improving the performance of epoxy asphalt pavement
