摘要
近年来国内外沥青路面技术愈发注重环保和低排放。受乳化沥青技术的发展所推动,冷拌沥青混合料开始步入市场,然国内尚没有专门针对该类混合料的材料设计指导规范。基于冷拌沥青混合料强度的形成规律,提出了适合于冷拌沥青混合料的试件成型方法及养生条件,可为冷拌类沥青混合料的设计提供参考。经室内性能验证,该冷拌沥青混合料具有较好的路用性能。
Asphalt pavement technology increasingly focused on environmental protection and low emis- sions in recent years. With the development and promotion of emulsified asphalt technology, the cold - mix as- phalt began to enter the market. However, there was no material design guidance specification specifically for the type of the cold - mix asphalt. In this study, the specimen molding and curing conditions for cold - mix asphalt were proposed based on its strength formation law, that could provide a reference design of the cold - mix asphalt. The results of pavement performance test showed that the cold - mix asphalt had better road per- formance.
