Epoxy Emulsifying Asphalt Mixture Research

Along with the deepening of China’s reform and opening uppolicy, the national economy has got rapid development. Road, a keyof the infrastructure, has made a great progress. But because of therapid growth, overload serious traffic flow, a few highway appearedmore serious early damage, also because of the low temperatureand the influence of water, highway can not be promptly and fastlyrepair. Epoxy emulsifying asphalt can be used in damp lowtemperature, and can improve road driving conditions, extend theservice life of the old road and other aspects. Therefore, the articleresearch epoxy emulsifying asphalt mixture.Epoxy resin is a kind of stable resin which is acquired in thefollowing method: the epoxy resin is dispersed in the form of particlesor droplet and using water as a dispersion medium. It is the biggestcharacteristic is the material is a kind of the hydrophilic polymer,which has low VOC content, can be cleaned by water, withoutexcitant taste, without any harm to human body, no pollution, and many other advantages. And epoxy emulsifying asphalt comparedwith general asphalt, its performance change from the hot solubleinto thermosetting, from one component into a two-component. Ittransforms cold crack, hot dissolve of the asphalt into thecharacteristics of high viscoelasticity in low temperature, and no meltin high temperature. Epoxy emulsifying asphalt because of itscharacteristics of thermosetting, form the network structure aftercuring cross linking; under repeated loading, low temperature, hightemperature condition it has no deformation, cracks, insoluble,viscous strength is obviously better than common asphalt andgeneral modified asphalt.Based on present situation and existing problems of epoxyemulsifying asphalt and its mixture, this article will mainly researchthe following aspects.1. Through the modification emulsified asphalt emulsion andmodification mechanism research, the article analyzes the epoxyemulsifying asphalt modification mechanism, and from its characteristics analyses the curing reaction of the process andproduction structure.2. Through analysising the influence of the epoxy resin, curingagent and emulsifying asphalt onemulsion of epoxy influence on theperformance of epoxy emulsifying asphalt,the article confirme theepoxy asphalt emulsion of reasonable formula, and put forward theperformance evaluation index.3. Basis on the preparation of epoxy emulsifying asphalt and thereference of Epoxy asphalt mixture of emulsified mix proportiondesign method and way-use performance in the system, the articleputs forward the modified Marshall test again gradation designmethod and way-use performance test methods. Road propertyresearch shows that, the epoxy emulsifying asphalt mixture has goodperformance of high temperature.4. Epoxy emulsifying asphalt mixture is a kind of cold mixingmaterials, and is different from hot mix asphalt mixture in construction process. It is necessary to pay attention to epoxyemulsifying asphalt mixture in the construction process.
