摘　　要：试验选用实际工程中常用的湖沥青、岩沥青改性AC-13、SMA-13混合料,对比分析了其性能优劣。结果表明天然改性沥青SMA-13型级配混合料各项路用性能均优于AC-13型级配混合料;湖沥青改性沥青混合料高低温性能优于岩沥青,有助于改善路面车辙和低温开裂问题;而岩沥青改性沥青混合料水稳性能和疲劳性能较湖沥青更好,有助于提高路面抗水损和抗疲劳性能。In this paper,the commonly used lake asphalt,rock asphalt modified AC-13,SMA-13 mixture in the actual project is selected,and its performance is compared and analyzed to provide a reference for the selection of pavement materials.The results show that the road performance of SMA-13 is better than that of AC-13;the high and low temperature performance of lake asphalt is better than that of rock asphalt,which helps to improve the rutting and low temperature cracking of pavement;the water stability and fatigue performance of rock asphalt modified asphalt is better than that of Lake asphalt,which helps to improve the water loss and fatigue resistance of pavement.
