Analysis Of Recover Methods And Equipment Erformance Based On Interitof RAP

Recycling of old asphalt pavement material, to solve the environmental pollutionproblem of the large amount of waste generated by the maintenance and reconstruction ofasphalt pavement, and reduce the demand for asphalt and gravel materials. Therefore, therecycling of old asphalt mixture has become an important issue to build a resource-savingand environment-friendly society. And the most important part of the asphalt concreterecycled is old pavement asphalt concrete material recycling, The integrity of the asphaltconcrete recycled material determines the regenerative capacity of these materials original,the higher the original regenerative capacity of the material itself, the means to restore thefewer the resources required for the performance of the old material, or the material cost ofthe entire regeneration process lower, which also makes the higher utilization of resources, tomaximize the effect of environmental protection.This article relying low carbon emissions scrap asphalt material the Hot Mixedrenewable technology "and" Jishan County, Shanxi Province Jingkun speed Hou Yu segmentsitu thermal regeneration "project over on the waste asphalt mixture recycling process, aseries of key technologies theory, ensure the integrity of the RAP material recycling.From the application point of view, recycling technology and equipment to do thefollowing:①RAP integrity of the material is divided into the level with integrity and the integrityof the asphalt performance and were elaborated and research, analysis of the asphalt mixturenature the RAP material level with the destruction of the law, asphalt aging mechanism. Fromthe the RAP material gradation integrity to start research cold crushing based recovery, tostart research based thermal fragmentation recycling integrity of the properties of asphaltfrom the RAP material.②By this stage of regeneration and recycling process, elaborated the advantages anddisadvantages of the in situ regeneration Mixing Plant regeneration from the recoveryprocess, recovery performance, energy loss and concentrated the cold milling crushing andcold scarifying broken Recycling ease of doing a detailed comparison.③Carried out based on cold crushing recycling research before conclusions mainly forthe cold milling recycling. From the the RAP material gradation integrity start with specificprojects, through the analysis of the the RAP material level with study milling machineoperating parameters and undermine the principle put forward a reasonable crushing process.④Thermal fragmentation-based recycling research. Start with the integrity of theperformance of asphalt from the RAP material, the pavement heating the asphalt pavementasphalt concrete material crushing process proposed conversion between heating machinerunning speed and heating effect.⑤Analyzed cold recycled milling secondary crushing and screening material, andrecycled materials stacked and sampling problems.
