SMA沥青混合料具有优良的抗车辙和抗低温变形能力,可大大改善沥青混合料的水稳定性,并且具有良好的抗滑性能,能有效延长沥青混凝土路面的使用寿命,降低后期养护成本,因此,现正越来越多地得到应用和推广,本文以新河高速公路为例,简要介绍SMA的关键技术指标及施工质量控制方法。 SMA asphalt mixture has excellent anti-rutting and low temperature deformation resistance, can greatly improve the water stability of asphalt mixture, and has good skid resistance, can effectively extend the service life of asphalt concrete pavement, reduce the cost of maintenance, so , Is being applied and popularized more and more. This paper takes Xinhe Expressway as an example, briefly introduces the key technical indexes of SMA and the construction quality control methods.
