摘　　要：采用60℃车辙试验,分析沥青标号、水泥掺量、泡沫沥青用量和养生时间对泡沫沥青冷再生混合料高温性能的影响。基于样本研究,得出如下结论:采用低标号沥青、增加水泥用量、延长养生时间均能够提高泡沫沥青冷再生混合料的高温稳定性;增加泡沫沥青用量会降低泡沫沥青冷再生混合料的高温稳定性。In this paper,60 ℃ rutting test is carried out to analyze influence to high temperature performance of cold recycled asphalt mixture by asphalt grade,cement content,foamed asphalt dosage and curing time. Based on sample study,it was concluded that using low grade asphalt,increasing cement content,prolonging the curing time can improve the high temperature stability of the foamed asphalt cold recycled mixture; increasing the amount of foamed asphalt will reduce the high temperature stability of the foamed asphalt cold recycled mixture.
