Method of Mix Design for Hot Recycled Asphalt Mixtures

Abstract:

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. This paper illustrates the mechanism of hot recycling of asphalts and proposes a simple and useful method of mix design for hot recycled asphalt mixtures. In the process, the performances and grading of reclaimed materials were evaluated. And the composition of raw materials with different contents were tested for selection of the best mix. The results show that the method is feasible by practise.
