介绍了 1 992年以来 ,集团公司发展部组织抚顺石油化工研究院等 7个科研、生产单位 ,对七·五期间开发、生产的重交通道路沥青所铺筑的 1 1 .4× 1 0 4m2 试验路长达 9年的跟踪观测和路用性能研究概况。经过 1 4～ 1 5年行车使用 ,大多数试验路仍然保持着良好的使用状态 ,各种常见路面病害发生的程度明显小于所在公路的邻近路段 ;回收沥青的老化速度比较缓慢 ,仍可继续使用。表明这些重交通道路沥青具有良好的路用性能和抗老化性能 ,完全可以替代进口沥青 ,满足我国高等级公路建设的需要
The article introduced seven research and production units of Fushun Research Institute of Petrochemical Industry, which were organized by the Development Department of the Group Company since 1992, covering 11.4 × 104m2 of asphalt paved with heavy traffic roads developed and produced during the Seventh Five-Year Plan period. Test Road up to 9 years of tracking and road performance profiles. After 14 to 15 years of driving, most of the test roads still maintained a good condition of use. The incidence of various common road diseases was significantly less than that of the adjacent sections of the road where they were used. The aging rate of recycled asphalt was relatively slow and could continue to be used . It shows that these heavy traffic road asphalt has good road performance and anti-aging performance, can completely replace imported asphalt and meet the needs of high-grade highway construction in China
