摘要
以AC-13F型改性沥青混合料为研究对象,通过浸水马歇尔和冻融劈裂试验、动稳定度试验,比较了不同掺量天然岩沥青混合料的水稳定性能和高温稳定性能,分析表明:天然岩沥青是一种性能优良的新型沥青添加剂,建议适宜的天然岩沥青掺量为8%。
With AC-13F type modified asphalt mixture as research object, the water stability performance and high temperature stability performance mixed with different natural rock asphalt mixture were compared with immersion Marshall and freeze-thaw cleavage experiment, dynamic stability experiment. The analysis indicated that the natural rock asphalt was a new asphalt additive with high quality property, the suggested proper natural rock asphalt mixing amount was 8 %.
