Experiment and Study on Compaction Characteristics of Warm Asphalt Mixture

Through the Marshall compaction tests and gyratory compaction tests,compaction characteristics of warm mix asphalt under different compaction methods are studied.With AC-13F,for example,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 compaction are greater than Marshall compaction;specimen volumetric property are not sensitive to compaction method and asphalt mixture type when the compaction times is 50.The contrast parameters for warm asphalt mixture design and construction are provided.
