The Application Analysis Of Asphalt Pavement Hot In-place Recycling Technology In Tuwuda Highway

Pavement Hot in-place recycling technology is one important method of asphalt pavement maintenance technology, high efficiency, environmental protection, low cost, traffic interference, in favor of inter-layer connection pavement, improve road grading, improve the structural strength of the road, the road delay aging and prolong pavement life and other characteristics and effects, is currently considered the most scientific, environmental and effective asphalt pavement maintenance techniques. In order to promote local heat regeneration technology in Xinjiang expressway maintenance practice, and effectively improve the effectiveness of road maintenance work in Xinjiang highway; I combine actual work, with a large black spit-speed pavement maintenance projects, for example, on the depth renewable geothermal technology applications.First, domestic and foreign perspectives summarized in situ thermal regeneration technology research progress and achieve results; secondly, from the concept, the core technology, technology type, application conditions and application advantages several angles, to place hot recycling concept was related summary explanation; again, by means of road damage index, with mass index, rutting index and structural strength index four indicators, a large black spit-speed road performance and status of the disease comprehensive investigation, analysis and evaluation; and finally, the system introduces the construction process before and after the thermal regeneration technology on a large black spit-speed pavement maintenance project is mainly the way of road maintenance, and construction into effect a comprehensive evaluation.Tuwuda highway pavement maintenance project confirmed the high-speed, hot in-place recycling construction technology is simple, better road maintenance, unrestricted construction period, while construction also occupies only one lane, traffic will minimize interference, the heaviest It is to achieve 100% recycling of old asphalt pavement materials, is consistent with the principle of resource recycling, has broad application prospects.
