Abstract: The effect of decreasing temperature of different warm mix asphalt additives is confirmed by Marshall Test． The influence of warm mix additive on porous asphalt mixture performance is researched． The results indicate that warm mix additive can decrease the mix temperature markedly，different warm mix asphalt additives have different effects of decreasing temperature，and the optimum mix temperature should be determined by compaction test． Warm mix asphalt additive A has no significant effect on road performance，but warm mix asphalt additive B improves high-temperature stability，and decreases water stability and anti-cracking performance．

Key words: porous asphalt mixture, warm mix additive, water stability, high-temperature stability, anti-cracking performance

摘要： 通过马歇尔标准击实试验确定了不同温拌剂的降温效果，通过路用性能试验研究了不同温拌剂对排水性沥青混合料性能的影响。试验结果表明: 温拌剂可以显著降低排水性沥青混合料施工拌和温度; 不同温拌剂降低温度的幅度不同; 最佳施工拌和温度应通过击实试验确定; 温拌剂A 对排水性沥青混合料路用性能没有显著影响，而温拌剂B 明显提高了排水性沥青混合料的高温稳定性，降低了其水稳定性与低温抗裂性。
