如何提高热熔型彩色沥青压实效果是其冬季施工的关键技术之一,对比了添加温拌剂前后热熔型彩色沥青性能指标、彩色沥青混合料和易性能的变化以及不同成形温度下混合料体积及强度指标。结果表明:温拌剂对彩色沥青老化后性能有一定改善效果,添加温拌剂明显提高了彩色沥青的和易性和压实效果,温度降低20℃能达到正常混合料性能水平,降低40℃以内,仍能满足规范要求。
How to improve the compaction effect of hot-melt color asphalt is one of the key technologies in winter construction. The performance indexes of hot-melt color asphalt before and after the addition of warm-mix asphalt, the change of easy-property and the change of color performance of asphalt mixture, Material volume and strength indicators. The results show that the warm mix agent can improve the performance of the color asphalt after aging, and adding the warm mix agent can significantly improve the workability and compaction effect of the color asphalt. When the temperature is lowered by 20 ℃, the performance of the normal mixture can be lowered and the temperature is lowered by 40 ℃ Within, still able to meet the regulatory requirements.
