Abstract:

Article Preview

Through analysis of densification curve characteristic of gyratory compaction, influence rules of the content of mineral aggregates of all sizes and asphalt on compaction characteristic of mixtures were studied. Test studies show that the mixture having more of asphalt has a faster density-increasing speed, that there is an optimal amount of fine aggregates for optimal compaction, and that an appropriate amount of mineral powder will improve workability of mixtures but overmuch mineral powder will make mixtures dry and hard. Conclusions from this research can provide basis for how to adjust material composition for improving compaction performance of mixtures.
