Method of Mix Design for Hot Recycled Asphalt Mixtures ...

Hot recycled asphalt mixtures are used more widely in road construction and reconstruction at present. The recycle of asphalts can reuse the waste asphalts and bring economic benefits. Meanwhile it can protect the environment and save the energy. The mix design is an important step for regeneration of the old asphalts. And it is critical to the performance of hot recycled asphalt mixtures.
