摘要： 通过沥青材料的密度灢温度关系以及集料的膨胀系数、温度与沥青蠕变性质、密度与沥青蠕变性质之间的关系,研究了密度和沥青蠕变性质与沥青材料的低温抗收缩裂缝性能之间的关系。结果表明,沥青材料的密度、蠕变劲度的对数、m 值与温度呈线性关系,沥青材料的蠕变劲度的对数和m 值与密度呈直线关系,沥青材料的密度与沥青的低温抗收缩裂缝性能密切相关,可以用密度与温度的关系判断沥青低温性能的优劣,判断结果与从蠕变性质判断的结果一致。

Abstract: The relationship between density and low temperature cracking with the densitytemperature relationship and coefficient of thermal expansion of aggregate,relationship between density and temperature,creep property and temperature,creep property and density was studied. The results show that the density, the Logarithm of the creep stiffness and m value are linear to temperature. The Logarithm of the creep stiffness and m value are all linear to density. The density is closely related with lowtemperature cracking performance.The relationship between density and temperature can be used to evaluate the performance in low temperature condition and the judgment of performance in low temperature is consistent with that from creep property of asphalt. 

Key words: Asphalt,    ,  Density,    , Creep stiffness,    ,  Lowtemperature performance
