摘　　要：对两种级配类型六种级配曲线进行了不同沥青用量下的60℃高温车辙试验,分析了沥青用量对高温性能的影响规律,指出沥青用量是影响混合料高温车辙的重要因素,且随着沥青用量的不断增大混合料抵抗高温变形的能力呈明显的下降趋势。最佳沥青用量并不是抵抗变形能力的最佳油量,而是混合料综合性能达到最佳的沥青用量。This paper has carried on 60℃ the high temperature wheel rut experiment under the condition of different asphalt amount used to two-kind of gradation type six-kind of grading curves,analyzed the asphalt amount usage to the high temperature performance influencing rule,pointed out that the asphalt amount usage is an important factor of affecting the blend high temperature wheel rut and the resistance high temperature deformation ability is decreased along with the asphalt amount usage increased.In addition,the paper also has confirmed that the best asphalt amount usage is not the best oil mass of anti-deformation ability,but the oil mass of blend overall performance achieving best.

关 键 词：沥青混合料 沥青用量 最佳沥青用量 高温车辙
