一、前言从国内外使用阳离子乳化沥青表明,阳离子乳化沥青具有良好的工作度,它可以均匀分布于矿料表面,因此,沥青用量一般可节省约约20％;还可节省能源,减少环境污染;施工时改善工人的工作条件;还可避免雨后不能立即施工的缺点。对阳离子乳化沥青国内外进行了许多研究,但为改善阳离子乳化沥青的性能在沥青材料上采用混合沥青,即石油沥青与少量的煤沥青混合,以改善阳离子乳化沥
I. Preface The use of cationic emulsified asphalt at home and abroad shows that cationic emulsified asphalt has good workability and can be uniformly distributed on the surface of mineral materials. As a result, asphalt content can be saved by about 20%, and energy saving and environmental pollution reduction can also be achieved ; To improve the working conditions of workers during construction; and to avoid the shortcomings of not being able to construct immediately after the rain. Many studies have been done on cationic emulsified asphalt at home and abroad. However, to improve the performance of cationic emulsified asphalt, mixed asphalt is used as the asphalt material, that is, the mixture of petroleum asphalt and a small amount of coal tar pitch is used to improve the cationic emulsified asphalt
