沥青与花岗岩碎石黏附性能改善技术研究
Research on Improvement of Adhesive Properties of Asphalt and Granite Gravel
摘要
Abstract
In view of the poor adhesion of acidic granite gravel and asphalt and the shortage of alkaline stone in asphalt pavement in China's expressway construction,this study evaluated the improvement effects of schemes,including single use of amine anti-stripping agent DRD-K1,single use of non-amine anti-stripping agent AMR-3,single use of cement,and combined use of anti-stripping agent and cement,on the asphalt-aggregate adhesion properties.Through the tests of three major indexes before and after asphalt aging,aggregate adhesion test,and improved water immersion method,the adhesion of asphalt was evaluated,and the optimal amount for use was proposed.The results show that the non-amine anti-stripping agent AMR-3 exhibits a better improvement effect than the amine anti-stripping agent DRD-K1,and 0.4%AMR-3+3%cement is the optimal anti-stripping solution.The research results can improve the application performance of acid granite in asphalt pavement,alleviate the shortage of stone resources,and reduce engineering costs.关键词
