摘　　要：文章总结了国内外提出的沥青混合料抽提及沥青回收方法,分析目前普遍使用的离心抽提试验及阿布森回收试验的不足。针对SMA混合料的特点,设计不同的对比试验,验证了SMA混合料抽提回收过程中,矿粉、三氯乙烯及纤维等关键因素的影响程度,并提出相应的解决方案与改进措施,以便准确评定SMA混合料的级配、油石比状况及混合料中的沥青性状;为进行正确的SMA配合比设计、分析SMA沥青路面的破坏原因及路用性能衰变规律以及SMA混合料的再生利用提供数据基础。The methods for extraction and recovery experiment on asphalt mixture are summarized, and the defects of the centrifugal extraction method and the Abson recovery method commonly used in recent years are analyzed. In view of the characteristics of stone matrix asphalt （SMA）, several different contrast tests are designed to research and verify influence of the key factors such as mineral filler, trichloroethylene and fiber during the process of extraction and recovery experiment on SMA mixture. Corresponding solutions to different influencing factors are presented so that the mix design for SMA can be made correctly, the destruction causes and the decay rule of SMA pavement performance can be researched, and the information needed for recycling and utilization of SMA mixture can be provided.
