摘　　要：在Evotherm(温拌技术作用原理分析的基础上,对温拌沥青混合料的施工时效、马歇尔体积指标、抗车辙性能进行了试验分析,得出温拌技术延长了有效施工时间,且在降温30℃范围内,马歇尔体积指标及抗车辙性能与热拌沥青混合料性能接近,由此说明温拌技术工艺效果是有效的,但同时也存在需要进一步解决的问题。Based on the theoretical analysis of Evotherm~ warm technology,the properties of warm mix asphalt were studied.The construction time limit,Marshall volume indexes and anti-rutting properties of warm mix asphalt were test.It is concluded that warm mix asphalt can increase the construction time,and have the same properties with hot mix asphalt between the 30℃ temperature difference.Observation from the test results indicated that warm mix asphalt is valid,whereas there are still some disadvantages for warm mix asphalt.
