摘　　要：通过系统地研究矿粉和回收粉的基本性质以及对沥青胶结料高、低温和疲劳性能以及沥青混合料高、低温和水稳定性能的影响,并对掺有矿粉和回收粉的沥青混合料路用性能做了一定研究。结果表明,在工程应用中根据实际情况适当采用经严格质量控制回收粉,既能保证沥青混合料的质量,又能节约建设资金,对于提高沥青混合料性能也有一定意义。This paper studied basic characters of mineral filler and reclaimed stone dust,its effect on high-low temperature perform- ance,fatigue performance of asphalt binder,and the effect on high-low temperature performance and water stability of asphalt mix- ture,as well as the performance of asphalt mixture with mineral filler and reclaimed dust used in road.The result shows that proper use on mineral filler and reclaimed dust under rigid control in project can assure the quality of asphalt mixture,save budget and even improve the performance of asphalt mixture.
