Abstract:Recycled asphalt mixture is made of the recycled asphalt pavement material (RAP) as the core raw material, and is added with new aggregates, new asphalt, regenerating agents and other materials. Through scientific proportioning and standardized construction, the recycled pavement material is formed, which has significant advantages such as resource recycling, energy conservation and environmental protection, and economic cost, and is an important technical path to achieve green and low-carbon development in road engineering. By integrating its core characteristics, quality control standards of raw materials, proportion design methods, and common disease prevention mechanisms, combined with experimental research and engineering practice, the mechanism of each influencing factor on the pavement performance of the mixture is clarified, and the key technologies and application experiences are sorted out, providing the scientific and rigorous technical support for the design, construction and maintenance of recycled asphalt mixture.
