The invention discloses warm mixing type colored asphalt cement.The warm mixing type colored asphalt cement is prepared from colored asphalt cement and RSA type modifier.The RSA type modifier is oxidized polyethylene and is formed by oxidizing linear low-density polyethylene with the molecular weight of 2,000-2,500.The admixing amount of the RSA type modifier in the warm mixing type colored asphalt cement is 2-10% of the weight of the colored asphalt cement by weight.The warm mixing type colored asphalt cement has the advantages of being good in high-temperature stability, low in construction temperature and environmentally friendly, saving energy and the like, the application range of color asphalt can be further expanded, and good social benefits and application prospects are achieved. 本发明公开了种温拌型彩色沥青胶结料，由彩色沥青胶结料和RSA型改性剂组成，其中所述RSA型改性剂为氧化聚乙烯，由分子量为2000～2500的线性低密度聚乙烯氧化而成；所述温拌型彩色沥青胶结料中RSA型改性剂的掺入量以重量百分数计为彩色沥青胶结料重量的2～10％。本发明的温拌型彩色沥青胶结料具有高温稳定性好、施工温度低、节能环保等优点，可进步拓宽彩色沥青的应用，具有良好的社会效益和应用前景。
