The Research Application Of Regenetated Technology Of Milled Asphalt Concrete Used To Expressway

With the extend of the expressway, the maintainance of road surface is getting large, theproblem produced by the abolish material is faced to us. Our expressways are mainly made withasphalt material .According to summary, there are about 4,000 million tons or so produced inexpressway maintainance, what has brought the waste of resource, economy damage andenviorment preserving. Under the condition, we began our research.The purpose of this thesis is based on the function analyze of asphalt milling materialproduced by the large and medium-sized expressway road surface maintainment engineering,combining with international and national asphaltt regenerate technology achievements,improving the function of asphalt milling material by mixing a certain scale of new material andnew asphalt or regenerate preparation, because of the serious ageing of old asphalt in millingmaterial, in order to conform to the norm of standard mixing material.Adding asphalt milling material handling equipments, and connecting it to existing mixingequipment, the regenerate technology can be hatched and industrialized. At the same time, thisproject can pave the experiment road to test the norms of technology achievements.This thesis not only can reuse lots of asphalt mixed material, increase the economicefficiency, but also can reduced the effection to envionmemt and the destroy to ecology resource,possessing excellent economic efficiency and social benefit.
