【摘要】 定量测定了沥青各组分与集料粘附性的大小。对沥青酸值、电性能、接触角、含蜡量及粘度与粘附性关系进行了探索。研究结果表明 :胶质、沥青质与各种矿料的粘附性最好 ,而饱和分与矿料的粘附性最差。施工中为提高沥青路面的抗水损害能力 ,应选择酸值较大、击穿电压小、蜡含量小及粘度较大的沥青更多还原

【Abstract】 Adhesions between different asphalt components to aggregate were accurately measured The relationship of asphalt acid number, electric property, wax content, contact angle, viscosity and adhesion was studied Experimental result showed that asphaltene has the highest adhesion to aggregate In order to improve the ability of water damage resistance ability, asphalt which has high acid number, low breakdown voltage, low wax content and high viscosity should be selected更多还原
