New production technique of SBS modified emulsion;

Research on SXK-1 modified emulsified asphalt;

As a new type of maintenance materials for asphalt pavement of expressway,modified emulsified asphalt have obtained much attention since it was exploited.

This paper introduces the characteristics of the technology of modified emulsified asphalt fiber coat and its use in the con- struction of road surface layer.

A new modified asphalt emulsion used for chip seal and it s performance;

Modified asphalt emulsion is being more and more used generally with the popularization of high-grade road surface and the improvement of the producecraft.

With the rapid developmint of polymer modified asphalt emulsion,polymer modified slurry seal,i.

In order to discuss the influence rule of mixture design key index in micro surfacing,the influences of stone types,gradation,mixture mix proportion and amount of modified emulsion asphalt on the mixing,time,and cohesion force index of mixture in micro surfacing,so as to provide reference.

In order to improve the temperature susceptibility of the emulsion asphalt, this paper researchs on two kinds of improving polymer and two kinds of homemade asphalt, using the experiment results and theories for emulsion asphalt and mixture, analyses the property of the modified emulsion asphalt.

With the technique applied in some expressway maintenance,the choice of the material(modified emulsion asphalt,aggregate,filler and water),mixing proportion and the construction technique have been discussed.

The SBR modified emulsified bitumen does for the highway under the sealing course,the tacky surface,was prompted forward the emulsified bitumen application step.
