Development and application of cationic asphalt emulsifier started late in 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 offer, improve the technological level of China's road to promote the development of the national economy. Sampling, laboratory: from the discharge port should be at room together without sampling, normal consumption conditions, due to the storage tank can be emulsified asphalt bitumen content of the emulsion is not different with inter-mixed with asphalt emulsifier, and therefore inaccurate. When asphalt emulsifier for asphalt content test recipes, used a small sample container about 50g asphalt emulsifier wholesale, heated on a hot plate evaporation 5-10min, until the temperature reaches about 160 ℃ can be measured. This approach can be used to determine pay attention evaporation of residual asphalt content, needs to do when the three objectives, the sampling should be 300-500g, ensure evaporation of residual bitumen reach more than 200g, heating evaporation to about 160 ℃, adhere to 30 min.
