本文介绍了S—Ⅰ型、S—Ⅱ型沥青表面活化剂(主要成份为有机酸胺和烷基胺)在道路工程中的应用情况。煤沥青中掺用该二种沥青表面活化剂0.1％,在渣油中掺用0.25％,能增加煤沥青及渣油与石子的粘结性,用掺有沥青表面活化剂的煤沥青和渣油铺成的路面,冬天不易开裂松散,夏季不易泛油发软。提高路面质量,延长使用寿命,提高了经济效益。沥青表面活化剂使用简单,不需添置设备,不增加繁重操作,不会影响施工进度。目前,沥青表面活化剂,在上海道路工程已全面推广应用,效果良好。
This paper introduces the application of S-Ⅰ and S-Ⅱ asphalt surface activators (the main components are organic acid amines and alkylamines) in road engineering. Coal tar pitch incorporates 0.1% of the two kinds of asphalt surface active agent, and 0.25% of the residual oil, which can increase the cohesiveness of the coal tar pitch and the residual oil with the stones. The coal tar pitch and the slag mixed with the asphalt surface activator Oil paved pavement, winter is not easy to crack loose, easy to pan oil in summer is soft. Improve the quality of pavement, extend the service life, improve economic efficiency. Asphalt surfactant is easy to use, without adding equipment, without adding heavy operations, will not affect the construction progress. At present, asphalt surface active agent in Shanghai road project has been fully applied, with good results.
