【摘要】：沥青胶结料性能、沥青用量、级配、孔隙率及外加剂是抗车辙性能的主要影响因素。本文结合理论分析与室内试验方法对沥青混合料抗车辙性能优化关键技术进行研究。结果表明:综合采用改性沥青与抗车辙技术,并借鉴Superpave与SMA混合料级配设计方法设计的抗车辙型沥青混合料具有良好的物理力学与体积指标;同时70℃条件下的动稳定度指标为3975次/mm,具有优越的水稳定性与高温性能;实体工程车辙深度跟踪观测表明车辙性能优化技术能够有效改善沥青路面抗车辙性能。
[Abstract]:Asphalt binder performance, asphalt content, gradation, porosity and admixture are the main factors affecting rutting resistance. In this paper, the key technology of rutting resistance optimization of asphalt mixture is studied in combination with theoretical analysis and laboratory test method. The results show that the anti-rutting asphalt mixture designed by adopting modified asphalt and anti-rutting technology and using the gradation design method of Superpave and SMA mixture for reference has good physical mechanics and volume index. At the same time, the dynamic stability index of 3975 times / mm, at 70 鈩，
