摘　　要：针对目前彩色透水沥青混合料缺乏统一技术标准的问题,选择了3种国内常用的彩色沥青品牌,通过沥青改性、混合料改性2种方法,对彩色透水沥青混合料性能进行优化。结果表明,优化方案难以兼顾规范对特种彩色沥青高低温性能的要求;沥青改性存在配伍性问题,需要非常高的掺量,经济性不佳;混合料改性的方法效果更好,专用改性剂可有效改善彩色透水沥青混合料的使用性能。In view of the lack of unified technical standards for colored permeable asphalt mixture,three commonly used color asphalt brands in China were selected to optimize the performance of colored permeable asphalt mixture through asphalt modification and mixture modification.The results show that the optimization scheme is difficult to meet the requirements of the high and low temperature performance of special colored asphalt;the problem of compatibility exists in asphalt modification and it requires a very high amount of asphalt,and the economy is not good;the method of mixture modification is better,and the special modifier can effectively improve the use performance of colored permeable asphalt mixture.
