The Research Of The Reunite SBR Modified Emulsified Asphalt Application In Maintain A Highway

Along with the highway fast development, the overload phenomenon also graduallyserious, and channel transportation increase the road corruption, so the problem of road surface quick and effect was put forward and nervures to be solved. Practice can prove that modified emulsified asphalt is a kind of effect material for rood surface maintain, and get more and more appreciafion and applicafion.The article studied the emulsifier compatibility with asphalt and modifying process, and also the condition to fulffll slow-setting and fast-curing, and laid a strong emphasis on the selection of emulsifier whit the corresponding material. Choose out the modifier,emulsifier,asphalt and stabilizer which meet the request through the study of the influence to the function of the Way which put SBR into emulsified asphalt, combine with the needs of producing equipments and product quantity we select the fit produce craft.The text studied the reunite SBR modified emulsified asphalt function characteristics through indoor experiment combine with the construction of road segments. We studied the slurry surfacing craft of modified emulsified asphalt through the construction of a lot of road segments and the conclusion of domestic and international construction experience, including the treatment before construction, design of mixture, construction machine, the control of construction process and the control of quantity, the research have important realistic meaning to the expansion of modified emulsified asphalt application.
