摘　　要：结合泡沫沥青冷再生混合料的室内试验,探讨确定泡沫沥青再生混合料最佳沥青用量的方法和最佳油石比。采用干劈裂强度、湿劈裂强度、干湿劈裂强度比、冻融劈裂强度比、马歇尔稳定度和浸水马歇尔残留稳定度进行综合性能分析,获得最佳沥青用量。Based on the laboratory test of foam asphalt cold recycling mixture,the determination method of the optimal asphalt content of foam asphalt recycling mixture is discussed.The optimal asphalt to aggregate ratio was determined through comprehensive performance analysis using dry splitting strength,wet splitting strength,dry wet splitting strength ratio,Marshall stability,residual Marshall stability in water immersion,and freeze-thaw splitting test strength ratio to obtain the optimal asphalt dosage.
