Analysis and Evaluation of the Recycled Asphalt Mixture Performance Influencing Factors

Abstract:

This paper is based on majority indoor tests of recycled asphalt mixture performance. To analyze the elements which could affect different blended rates of the old material and the different mixing processes of recycled asphalt mixture by using orthogonal experiment method. The results show that, different mixing processes have significantly influenced the performance of rutting resistance on the high temperature, resistance to water damage of the recycled asphalt mixture. However blending rate of the old material has influenced more on low-temperature crack resistance of the recycled asphalt mixture. Old material blended rate is 30% and first mixing of old materials and recycling agent in a hot-melt state, by adding new complementary stone , followed by a new supplementary asphalt mineral powder mixing process to produce recycled asphalt mixture for an ideal performance.
