泡沫沥青混合料是一种全新的道路材料,其有关特性尚不完全清楚。通过大量试验,分析了泡沫沥青再生混合料物理力学性能的影响因素。研究得出,铣刨料中沥青含量的多少直接影响着泡沫沥青再生混合料的高温稳定性;铣刨料的含量影响着混合料的密度和空隙率;用于再生混合料的沥青黏度与混合料高温稳定性成正比关系,沥青延度与劈裂强度成正比关系。
Foamed asphalt is a new road material, the relevant characteristics are not yet fully understood. Through a large number of experiments, the factors affecting the physical and mechanical properties of foam asphalt mixture were analyzed. The results show that the content of asphalt in milling material directly affects the high temperature stability of recycled foam asphalt mixture. The content of milling material affects the density and voidage of the mixture. The viscosity of the asphalt mixed with the mixture The material is proportional to the high temperature stability, asphalt ductility and splitting strength is proportional to the relationship.
