温拌沥青混合料WMA(Warm Mix Asphalt)是一种新型、环保路面铺筑材料,它使用一种具有合适粘度的调和沥青,即由两种不同针入度的沥青(软沥青和硬沥青)混合而成,从而可以使沥青混合料在较低温度下拌和、压实与施工,但仍具有与传统的热拌沥青混合料(HMA)相同的路用性能。该文主要介绍Aspha-Min,Sasobit和Evotherm 3种不同添加剂对温拌沥青混合料路用性能的影响。
WMA (Warm Mix Asphalt) is a new, environmentally friendly paving material that uses a blend of bitumen of suitable viscosity, namely, bitumen (soft and hard bitumen) , Allowing the asphalt mix to be compacted and compacted at a lower temperature while still providing the same road performance as a conventional hot mix asphalt (HMA). This paper mainly introduces the influence of Aspha-Min, Sasobit and Evotherm additives on road performance of warm-mix asphalt mixture.
