中文摘要	基于室内试验并以AC13为例,对空隙率与沥青饱和度和吸水率、沥青混合料力学性能(模量、劈裂强度,抗剪强度)、冻融劈裂强度(比)及疲劳寿命间关系展开研究.研究结果表明:空隙率影响沥青混合料性能,其间存在很好的相关性;随着沥青混合料的空隙率增大,沥青饱和度降低,吸水率增大;空隙率增大,沥青混合料力学性能(模量、劈裂强度、抗剪强度)降低;空隙率增大,沥青混合料冻融劈裂强度降低,冻融劈裂强度比减小,沥青混合料抗水损坏性能降低;随着空隙率增大,沥青混合料剪切疲劳寿命减少.; The effects of air void content on asphalt mixture performance are investigated. Based on performance-related tests at laboratory and as an example of AC13,the relationships between air void content and voids filled with asphalt (VFA),water absorption,mechanical behaviors (including low-temperature splitting failure stiffness modulus,splitting strength and shear strength),freeze-thaw splitting strength (ratio) and fatigue life of asphalt mixture were analyzed. The research results show that air void content influences asphalt mixture performance and there exists an obvious relationship between them;with the increase of air void,VFA lessens and water absorption increases;mechanical behavior of asphalt mixture decreases when air void increases;with the increase of air void,freeze-thaw splitting strength (ratio) decreases,which indicates that anti-moisture behavior of asphalt mixture lessens;shear fatigue life of asphalt mixture also decreases with the increase of air void.; 国家杰出青年科学基金项目(批准号:50325825); 中国博士后基金项目(批准号:20060390446)资助
