稀浆封层和同步碎石作为道路下封层工艺的对比研究

黑色沥青路面是我国路面重要的结构形式,被广泛应用于各等级公路路面结构层.该结构层通常由沥青混凝土混合料面层(包括上中下层)、无机结合料稳定粒料半刚性基层或水泥稳定碎石刚性及半刚性基层以及垫层组成.为了提高路面的承载力、耐久性和抗水毁能力,对于沥青混凝土路面各层间的处理也越来越受到重视.这种多层次结构在设计与施工时,其层...

Comparison and Study of Slurry Seal Coat and Synchronous Surface Dressing as Road Lower Seal Coat Technology

The black asphalt pavement is the important structural type of pavement in China and is widely applied in the pavement structural layer of various highways.This structural layer is commonly composed of asphalt concrete mixture surface(including the upper,middle and lower layers),inorganic binders stabilized gravel semi-rigid base or cement stabilized macadam rigid and semi-rigid base and cushion.In order to enhance the carrying capacity,durability and anti-water damage capacity of the pavement,more importance is attached to the treatment among the layers of asphalt concrete pavement.During the design and construction of this multi-layer structure,the combination of the layers is very important especially the combination of the surface and base.The article compares and studies several lower seal coat technology commonly used in China so as to further efficiently enhance the service life of road and to prevent the roads from the faults.
