摘　　要：通过马歇尔击实试验和旋转压实试验,研究不同压实方式对温拌沥青混合料压实特性的影响。以AC-13F为例,分析了成型方式和压实次数对温拌沥青混合料体积参数的影响,并采用热拌沥青混合料进行对比。结果表明:采用旋转压实法成型的试件密度大于击实法;在压实次数为50次时,试件体积参数对成型方法和沥青混合料类型均不敏感等,为温拌沥青混合料的设计和施工提供了对比参数。Through the Marshall compaction tests and gyratory compaction tests, compaction charac-teristics of warm mix asphalt under different compaction methods are studied . With AC-13F , for exam-pie, the impact of compacting method and compaction times on volumetric property of warm mix asphalt are analyzed and compared with hot mix asphalt. The results show that specimen density by gyratory com-paction are greater than Marshall compaction ; specimen volumetric property are not sensitive to compac-tion method and asphalt mixture type when the compaction times is 50. The contrast parameters for warm asphalt mixture design and construction are provided.
