掺加橡胶颗粒的沥青混合料性能研究

Study on Performance of Asphalt Mixture Mixed with Rubber Particles

通过CAVF法进行混合料的级配设计与传统的沥青混合料级配对比分析,在不同的橡胶颗粒掺量条件下研究JDAC-16的沥青混合料路用性能,试验结果表明,掺量3%的橡胶粉可以明显改善沥青混合料的高温、低温及抗水损害性能,而超过适宜掺量反而会劣化混合料的性能。

According to the grading design of mixture by CAVF method and the grading comparison and analysis of the traditional asphalt mixture, the pavement performances of JDAC-16 asphalt mixture are studied under the condition of the different mixing amounts of rubber particles. The test result shows that the mixing amount 3% of rubber powder can obviously improve the high-temperature, low-temperature and anti-water damage performances of asphalt mixture, but the exceed appropriate mixing amount will degrade the mixture performance.
