摘　　要：通过不同沥青混合料的多温度马歇尔试验和劈裂试验,分析马歇尔稳定度与劈裂强度两项指标随温度的变化规律,建立两者的温度函数,这项研究发现,劈裂强度与稳定度两者的温度函数都符合指数函数,而且试验结果表明,两个温度函数在反映不同沥青混合料的稳定度与劈裂强度随温度增减的速率方面具有一致性。Based on asphalt mixtures tests of Marshall stability and tensile strength at different temperatures, the development trends of the two technical indexes with temperature change were analyzed and temperature functions of the two technical indexes were established. The result indicated that the temperature functions of Marshall stability and tensile strength both belong to exponential function. And it shows that the different mixtures Marshall stability change rates with temperature are in coincidence with those of the tensile strength by the experiments.

关 键 词：沥青混合料 稳定度 劈裂强度 温度函数
