? ?? Asphalt emulsifier technology is the normal temperature of a means of hot asphalt construction technology, because of its room temperature operation, saving energy, especially for the protection of the environment has benefits, but the use of emulsified asphalt just a scratch in the form of process Its performance remains the ultimate expression of the basic properties of asphalt. Asphalt emulsifier generally on asphalt material properties can be roughly divided into four types: First: asphalt emulsifier in the original asphalt emulsion breaking enable performance improvement; second: asphalt emulsifier in the emulsion breaking energy asphalt to maintain the original performance; third: asphalt emulsifier http://www.hnsdyhg.com/ after breaking asphalt emulsion original performance slightly lower; fourth: asphalt emulsifier in the emulsion breaking asphalt a significant reduction in the original performance. ?? The impact can be seen on the asphalt asphalt emulsifier performance can be summarized as follows:?? A. Types of asphalt emulsifier, the different effects of different types of asphalt emulsifier for asphalt material properties;?? B. Asphalt emulsifier, asphalt emulsifier with a different time, a different impact on the performance of bituminous material;?? C. Asphalt emulsifier asphalt material properties affect the quality of the pros and cons of different little general impact of high quality pure asphalt emulsifier for asphalt material properties, poor quality impure material properties of bituminous asphalt emulsifier will significantly decrease. --zhongqi
