New Emulsified Asphalt Mixture And Repair Technology

New-type of Emulsified asphalt mixture is a kind of pavement material of good performance for patch. It has the advantages of high-efficiency, enegey-save, speediness and low pollution.It is not restricted by climate, and store in plastic bag, and be used at any time for repair. It has the extremely vital significance to give full play to the usability of road.In this paper, through the analysis of asphalt emulsification mechanism, Emulsified asphalt preparation mechanism, and Emulsified asphalt stability mechanism, a conclusion has been arrived at that water solute cationic emulsifier mixed with oil soluble non-ionic emulsifier has better effects than the single use of cationic emulsifier.Two new kinds of emulsified asphalt which are applicable for long-term storage are made out after a great deal of experiments. The qualities of the asphalt emulsion is checked, and they satisfy the requirements of BC-2 cationic asphalt emulsion and could be used as binding material.Through the analysis of structural features and strength mechanism, Choose the dense framework-graded.By using the Corrected Marshall experiment method to determine water-consumption and best asphalt content, to ensure that the emulsified asphalt mixture have a certain initial strength and forming strength. Meanwhile,This article also complement the emulsified asphalt mixture workability, storage, initial strength, forming strength, cohesiveness, water stability and other aspects of the research system and, based on performance characteristics of emulsified asphalt mixture, made up for the emulsified asphalt mixture performance evaluation and criteria. And will it compared with the hot mix.Finally, this article is introduces emulsified asphalt mixture production technology, storage method and construction technology, and also analyzes the economic and social results of the Emulsified asphalt mixture.It is better than hot mix not only in social, economic, but also in environmental benefits.
