摘要
南方地区受高温多雨气候的影响以及行驶车辆重载化趋势日益严重,在高等级道路沥青路面中的沥青材料逐渐向黏度大、软化点高、抗车辙能力强的方向选择。研究开发的三种高黏沥青具有黏附能力强、高温性能优异的特点,在透水沥青路面、超薄层磨耗层路面、钢桥面上应用取得良好的效果,为不同类型路面用沥青的开发提供技术经验以及工业生产应用案例。
Due to the influence of high temperature and rainy climate in the southern region,as well as the increasing trend of heavy loading of vehicles,asphalt materials in high-grade road asphalt pavements are gradually being selected towards high viscosity,high softening point,and strong resistance to rutting.The three types of high viscosity asphalt developed through research have the characteristics of strong adhesion abil-ity and excellent high-temperature performance.They have achieved good results in the application of perme-able asphalt pavement,ultra-thin wear layer pavement,and steel bridge deck,providing technical experi-ence and industrial production application cases for the development of asphalt for different types of pavement.
