Research and Application of Warm Recycled Asphalt Mixture

Abstract:

Reclaimed asphalt pavement (RAP) develops rapidly throughout the world. Hot recycling is one way to make effective use of the waste, but the percentage of RAP in hot recycling is no more than 30%. By way of warm asphalt technology, the percentage of RAP can increase greatly. In this paper, warm recycling is researched. The RAP and the virgin materials including aggregates and asphalt are tested and analyzed. Then, two warm recycling mixtures with different amount of RAP are designed and their properties are investigated. As a comparison, the performances of hot recycling are also tested. At last, the performances of warm recycling and hot recycling are compared and discussed. After the laboratory research, the warm recycling made its debut in Beijing and it exhibit very well, which testifies that warm recycling owns good properties. Warm recycling can make use of pavement waste, and it can decrease the emission and energy consumption. Warm mix is environment-friendly and it is promising in the near future.
