Influencing Factors Research on Compaction Effect of Coarse Rubber Granule Asphalt Mixture

Abstract:

Dry process was taken by coarse rubber granule replacing coarse aggregate of the same volume. By an orthogonal experiment, a combined method of vibration compaction and Marshall compaction was used to study main influencing factors on compaction effect of coarse rubber granule asphalt mixture, making voidage as guidepost. The experiment results show that the most prominent influencing factor is rubber content, secondly the influencing factors are compaction temperature, vibration frequency and vibration time, the least is compaction times. An optimal compaction process for the coarse rubber granule asphalt mixture is put forward.
