花岗岩沥青混合料水稳定性能改善试验研究

Experimental Study on Improving Water Stability of Granite Asphalt Mixture

花岗岩是一种酸性石料,它具有强度高,耐磨性等优点。但是由于花岗岩和沥青的粘附性不好,往往因为达不到相应的设计要求而影响到花岗岩沥青混合料的运用。本文通过对掺加消石灰、水泥、改性剂、消石灰水代替矿粉等处理方法进行对比试验研究,探索改进花岗岩沥青混合水稳定性的最优方法,以期为工程实践提供借鉴。

Granite is an acidic stone with high strength and wear resistance.But due to the poor adhesion of granite and asphalt,the use of the mixture is often affected because it couldn＇t meet the corresponding design requirements.Based on the comparison tests for approaches as mixing the lime, cement,modifier,lime water instead of the mineral powder in engineering,the best practices are explored here to improve the water stability of the granite-asphalt mixture,which would be expected to provide guidance for engineering practices.
