摘要
温拌沥青混合料是拌和温度介于热拌沥青混合料和冷拌沥青混合料之间,性能接近热拌沥青混合料的新型路面材料的统称。对基于Evotherm温拌技术的AC类密级配温拌沥青混合料与同级配的热拌沥青混合料在水稳定性、高温稳定性、低温性能、疲劳特性、抗剪切性能等方面进行了全面的对比分析,结果表明:Evotherm温拌沥青混合料性能可以达到热拌沥青混合料的技术要求,其疲劳性能优于热拌沥青混合料。
Warm mix asphalt (WMA) is a kind of innovative pavement material of which the mixing temperature is between hot mix asphalt (HMA) and cold mix asphalt and the performance of which is close to HMA. The paper compared the performance of Evotherm warm mix asphalt of dense gradation with hot mix asphalt of the same gradation in all aspects, including water stability, high-temperature performance, low-temperature performance, fatigue properties and shearing properties. It is shown that the performance of WMA meets the requirement of traditional HMA and the fatigue properties are better than HMA of the same gradation.
