To boost the development of colored asphalt pavement,focusing on the ULTC warm mix colored asphalt mixture,this paper used the equal void ratio method to determine its compaction temperature,tested its stability and flow value under different compaction temperatures,and analyzed its warm mix characteristics.The high-temperature rutting resistance,low-temperature cracking resistance,and water stability of the ULTC warm mix colored asphalt mixture were tested,and the on-site ULTC warm mix colored asphalt test road was paved.The study results showed that the minimum compaction temperature of the ULTC warm mix colored asphalt mixture based on the equal void ratio method was 112℃;under the same condition,the dynamic stability of the hot mix colored asphalt mixture was larger than that of the warm mix colored asphalt mixture,while the flow value was smaller,so additional curing time was recommended during actual construction.The ULTC warm mix colored asphalt mixture's high-temperature properties,low-temperature properties,and water stability all met the specification requirements,and the on-site test road performed well,realizing the combination of the warm mix technology and colored asphalt technology.
