Abstract: How to improve the effect of hot melt type color asphalt compaction is one of the key technology in the winter construction Indicators of hot melt type colored asphalt before and after adding warm mix agent was compared, and the volume and intensity index under different forming temperature was also compared The results showed that aging performance of the asphalt could be improved and the effects of low temperature compaction could be also enhanced by the agent The indicators still could meet the specification requirements even the indoor molding temperature reduced within 40.
