Research on The Experiment of the Time Rule of the Demulsification about the Cold Recycling Emulsified Asphalt Mixture in view of the Gradation Demulsification

The paper in order to solve the problems and technical difficulties of emulsified asphalt cold recycling mixing plant, which can promote the application and promotion of the technology in Liaoning Province. It developed an emulsified asphalt cold recycling mixture that can achieve levels of breaking, and analyzed the time rule of the demulsification about the cold recycling emulsified asphalt mixture in view of the gradation breaking under different factors. And the paper also makes an analysis of its road performance. Based the premise of the substantially unchanged performance, the additives, the pH of emulsion and the temperature of mixing that can be used to change the time rule of the demulsification about the cold recycling emulsified asphalt mixture. In addition, the road performance of cold recycling emulsified asphalt mixture in view of the gradation is better than the normal cold recycling emulsified asphalt mixture. The technology of the emulsified asphalt cold recycling mixing plant in view of the gradation can effectively solve the current technical problems and defects of asphalt emulsion cold recycling.
