【摘要】：利用接触角法研究沥青-石料粘附性来预防沥青混合料水损害已成为近年来的研究热点。本文采用接触角法,以公路建设中常用的七种石料和三种沥青作为研究对象,以期得到同一、稳定的试验条件来研究材料的本征参数对沥青-石料粘附性的影响。结果表明,试样经过15.9 mm抛光度抛光、蒸馏水-无水乙醇-环己烷-蒸馏水依次清洗、60℃试验温度条件下进行接触角试验,所得沥青-石料粘附功与材料本征参数影响沥青-石料粘附性的结果相对应。
[Abstract]:Using contact angle method to study the adhesion of asphalt and stone to prevent asphalt mixture water damage has become a research hotspot in recent years. In this paper, seven kinds of stone and three kinds of asphalt, which are commonly used in highway construction, are used as research objects. In order to obtain the same and stable test conditions to study the influence of the intrinsic parameters of the material on the adhesion of bitumen to stone, the results show that the sample has been polished with a polishing degree of 15.9 mm. The contact angle test of distilled water, ethanol, cyclohexane and distilled water was carried out at 60 鈩，
