摘要
文章结合柳州绕城高速公路AC-13(改进型)沥青混合料矿料级配,利用SGC旋转压实机成型沥青混合料试件并进行劈裂试验,对AC-13(改进型)沥青混合料的间接抗拉强度进行评价,得出沥青混合料的空隙率、油石比、老化这些指标的变化与沥青混合料的力学特性间的密切关系。
With reference to the AC-13 (improved type) asphalt mixture gradation for Liuzhou ring road expressway,the Paper conducts a splitting test with the asphalt mixture specimen made by SGC rotating compactor,and makes an assessment on the indirect tensile strength of AC-13 (improved type) asphalt mixture.And it finally concludes that the variations in porosity,oil/rock ratio and aging index of asphalt mixture are closely related to the mechanical properties of asphalt mixture.
