厂拌热再生沥青混合料路用性能影响因素分析

Study on Influence Factors on the Performance of Hot Plant Mix Recycled Asphalt Mixture

采用灰色关联法分析再生沥青混合料的高低温性能、水稳定性与各技术指标的关系,从而找出了主要的影响因素。试验结果表明,空隙率对再生沥青混合料路用性能影响最大,在设计过程中和实际生产时,空隙率应成为主控因素,以延长路面使用寿命。

This paper analyses relations of recycle asphalt mixture behaviors at high and low temperatures and its water stability to various technical indexes using grey relevant analyses method to find the main influencing factors. Test results indicate that void ratio has great influence on road performance of recycle asphalt mixture, and in design and production, the void ratio should be chiefly-controlled to prolong the pavement service life.
