温拌沥青混合料的应用研究

Study of Application of Warm-Mix Bitumen Mixture

温拌沥青混合料是一种节能、环保的路面新材料,它的生产施工温度介于热拌沥青混合料与冷拌沥青混合料之间,其拌和温度为120℃左右,摊铺温度为100℃左右。温拌沥青混合料力学性能和路用性能不亚于传统的热拌沥青混合料,但生产施工温度可以降低30～50℃,具有明显的经济社会效益和环保作用。

Warm-mix bitumen mixture is a kind of pavement material with energy saving and environmental protection, with a moderate temperature of production and construction between hot aspholt mixture and cool asphalt mixture, about 120℃ of mix temperature and 100℃ of paving temperature. The mechanical and road performances of warm-mix bitumen mixture are not less that of traditional hot-mix bitumen mixture, but the temperature of production and construction can reduce to 30 - 50 ℃ so as to have remarkable social and economic benefit and environmental protection function.
