橡胶粉、火山灰复合改性SBS沥青性能的分析

摘要

In this paper, SBS asphalt material is modified by adding rubber powder and volcanic ash. Through the microscopic observation, the composite theory is used to improve the stability of the high temperature and low temperature of the material. It is used to improve the material properties of asphalt pavement in seasonal freezing areas and crack resistance, and to provide support for ensuring the highway's good service conditions.%本文主要针对SBS沥青材料通过添加橡胶粉、火山灰进行改性,通过微观观测,采用复合理论对材料提高高温、低温稳定性能方面进行分析,为季节性冰冻地区沥青路面抗车辙、抗裂缝在材料性能上进行改善,为公路保证良好的使用条件提供支持.
