China started the development and application of cationic asphalt emulsifier late asphalt emulsifier wholesale, 1977 successfully developed in 1978 by the Transport Ministry to complete the "cationic emulsified asphalt and road performance" issues Collaborative Group. Cationic emulsified asphalt for the development of a lot of work. 1981 as a research project focused on the Ministry of Transportation, in 1983 as the State Planning Commission and the Economic Commission for saving application projects. 1985 by the Ministry of Transportation conducted a technical appraisal. And decided to promote the use of a nationwide "Plan" period. 1987 held in Hangzhou cationic emulsified asphalt promotion, and made 1990 one-third of China's road cationic asphalt emulsifier. So far, the country has 14 provinces and cities have been widely used in road building roads, due to the shortage of raw materials, production of cationic asphalt emulsifier far failed to meet the needs of practical application in the future to new varieties of domestic and cationic asphalt emulsifier prepared strengthen the process development and application of asphalt emulsifier formulation, improve the technological level of China's road asphalt emulsifier, to promote the development of the national economy. Adsorption phenomena asphalt emulsifier molecules in an aqueous solution of orientation, not only between the air and the water phase, may also occur in bituminous phase than air. This adsorption phenomenon physical adsorption and chemical adsorption, via chemical adsorption, with the increase of carbon chain length of the lipophilic adsorption speed, adsorption speed to accelerate the molecular orientation of the surface of the water and finally forming a single molecular layer, so that the water Surface tension reduction.
