| Along with the use of the expressway extension, there will be a group of highways, which enter a period of maintenance and upkeep. Micro-surface is a cost-effective preventive conservation technique.This subject initiates new research contents and research methods on the basis of combination of engineering practice and using for domestic and foreign reference, which design detailed study about microsurface the material and mixture. Discuss modified asphalt emulsion mechanism, analyze the factors which impact comprehensive performance of modified asphalt emulsion, investigate different nature of modified asphalt emulsion, choose a suitable emulsifier, and establish the appropriate dosage. Analysis stable emulsion storage mechanism, evaluates stability of the type and dose of modified asphalt emulsion stability and other properties, and provide a reasonable and effective improvement measures. Making trials for selection of the raw materials and technical indicators. Do the research for Microsurface design methods. |
