Study On An Environmental Ice-deicing And Snow-melting Coat For Asphalt Pavement

In winter,the snow and ice on the Asphalt Pavement do harms to the traffic,limiting thedevelopment of the transportation industry and bringing the inconvenience to people’sliving.Deicing and snow melting has becomes one of the important works of themaintenance department.The technologies of deicing and snow melting now existdisadvantages and need more further reseaches urgently.In this paper,a large number ofstudies has been made and provides an environmental coating technology which can deicingice and melting snow initiatively.First，the paper certifies that it can lower the freezing point by add some kind of thingthrough the studying of the principle of freezing point depression.Then,the study of theadhesion of coating and pavement and the substances slowly releasing has been made andmade out the intermixture of the coat which can deice ice and melt snow.The testing foundthat the intermixture is endurable and good at deicing ice and snow melting.Compared withthe ordinary deicing salt,the coat does harms to no plants,nor corrosion to steel.Afterthat,the paper studies the construction process of the coat and presents matters needingattention to the pre-construction and construction.In the end,the performance of thepavement skid after the coating is analyzed.
