摘要
为提高透水沥青混合料的水稳性,对掺加4种不同长度的短切玄武岩纤维和北美孚玄武岩纤维透水沥青混合料进行浸水马歇尔试验和冻融劈裂试验,对比分析了不同长度及不同种类的玄武岩纤维对其水稳性的影响。研究表明,在PAC-13级配中,短切玄武岩纤维可以提高透水沥青混合料的水稳定性能。
In order to improve the water stability of permeable asphalt mixture, the immersion Marshall test and freeze-thaw splitting test of four kinds of short cut basalt fiber and North American phaltic basalt fiber permeable asphalt mixture were carried out. The effects of different lengths and types of basalt fibers on its water stability were compared and analyzed. The results show that the chopped basalt fiber can improve the water stability of permeable asphalt mixture in PAC-13 gradation.
