Research and Application of Factory Mixed Hot Recycled Asphalt Mixture Based on Cold Addition in Guangzhou Municipal Roads
Based on the Guangzhou Municipal Road Maintenance Project,this study explores the engineering application of factory mixed hot recycled asphalt mixture with cold additives in the Guangzhou area.The mix design and production process optimization of factory mixed hot recycled asphalt mixture with cold addition of recycled asphalt pavement material(RAP)was studied,and the high-temperature performance,water sta-bility,and fatigue resistance of the recycled asphalt mixture was tested.The results show that reasonable mate-rial design and production process optimization can ensure the road performance of factory mixed hot recycled asphalt mixture under cold addition,and can be promoted and used in practical engineering.
