Flexible Foam Asphalt Recycled Concrete Half Complete Sets Of Technology Research At The Local Level

Now, with a lot of repair and maintenance of highways each grade and transformationphases, each year about12%of the surface to be overhauled, the initial estimate of wasteevery year only amounted to2.2million tons highway pavement, and how these techniquesusing recycled waste materials for recycling, used for road repair, change, expansion or newconstruction, both beneficial to the environment, but also save a lot of investments.Foamed bitumen cold recycling is undoubtedly an ideal technology.This paper mainly deals in Tianjin foamed asphalt pavement recycling materials usedare recycled for a special research, mainly from raw material characterization, foamedasphalt mixture performance regenerative research, construction technology and on-sitequality control research, technical and economic analysis of several aspects of the relevanttests. Now more commonly studied several bitumen foaming properties and foamingproperties of bitumen of parameters. Through the foamed asphalt mixture performance ofrecycled obtain the material’s physical and mechanical properties, analyze gradation andthe correlation between these indicators. According to the construction site, a reasonableconstruction technology and quality control standards, and foamed bitumen cold recyclingtechnology for technical and economic analysis.
