摘要
云南地处低纬度高原,气候条件特殊,常规热拌沥青混凝土路面易产生早期破坏,而温拌技术的采用将能弥补热拌技术在云南地区应用的不足,满足经济建设的需要。本文对采用Evotherm温拌技术的密级配温拌沥青混合料(AC-13)与采用相同矿料级配的热拌沥青混合料分别在各自最佳油石比条件下进行了性能测试,对比两者在热稳定性能、水稳定性能、疲劳性能、压实效果等方面的差异,并分析了Evotherm温拌技术在云南地区的工程应用价值。
Yunnan is located in low-latitude plateau and the climatic conditions is special ,so conventional hot-mix asphalt concrete pavement is easy to produce an early destruction. The application of the evotherm warm mix asphalt technology will be able to compensate for hot-mix application of technology in the Yunnan region enough and to meet the needs of economic construction. The paper compared the Evotherm warm mix asphalt technology of dense gradation with hot mix asphalt of the same gradation in some properties, including hot stability, water stability ,fatigue properties and compress result and analyzed the engineering application value of the evotherm temperature asphalt mixture technology in Yunnan.
