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.
It is a hot spot to study the asphalt-stone adhesion to prevent the water damage of asphalt mixture by the contact angle method.In this paper, seven kinds of stone materials and three kinds of asphalt commonly used in road construction are studied by contact angle method in order to obtain the same and stable experimental conditions to study the influence of the intrinsic parameters of materials on the adhesion of asphalt-stone.The results show that the contact angle test is carried out at the temperature of 60 ℃ when the sample is polished by 15.9 mm polishing degree, washed with distilled water-anhydrous ethanol-cyclohexane-distilled water.The obtained asphalt-stone adhesion work corresponds to the result of the material intrinsic parameter affecting the asphalt-stone adhesion.
