The Application Analysis And Economic Evaluation Of Cold Recycling Technology In Fuxin

After many years of difficult transition in Fuxin, rapid economic growth and ecological environment is improved. Highway is an important medium for economic development; Fuxin Government has to invest a large amount of financial and material resources used for road repair and maintenance every year. Huge and necessary expenditures enable the highway to promote recovery in Fuxin at the same time, also slows the rate of economic growth. Additionally, a large number of Fuxin mining of sand and trees are also contrary to the "construction of Garden City" in the first place. Although there are many constructions in Fuxin area for cold recycling technology and economy, environmental protection, it has not yet formed a complete theoretical system. Therefore, in order to meet the needs of Fuxin economic development and environmental protection, this paper focuses on the study of cold recycling technology to enable the technology to be better serve development in Fuxin.This paper sets Fuxin Yuhong and Yingbin street cold recycling project as an example, according to the order of design, construction, evaluation research on cold recycling technology, is divided into four phases:Design phase of the scheme, demonstrates evidence and methods for selection of overhaul based on an example of test road, summarizes the design process and steps; mix design stage, analyses of gradation composition of the old road milling materials, measures maximum dry density and optimum moisture content of specimens under different amounts of cement, determines testing road with cement content of 5% or 6% based on unconfined compressive strength,15% is the best of coarse aggregate volume; The construction phase, through the test road paving, elaborates on the construction technology of cold recycling, forms a more complete theoretical system construction. The evaluation phase, analyses feasibility, economic reasonableness and social benefits of cold recycling technology. Evaluation its social benefits, can be divided into Socio-economic and ecological environment benefit, and focuses on demonstration of environment benefits, it presents and demonstrates the theory of sustainable development can be as theoretical basis of the evaluation of environmental benefits of cold recycling technology, while introduces technology clean concept, points out that technology clean is the embodiment of the theory of sustainable development technology, technology clean is practical as evaluation of cold regeneration technology of environment benefits, it gives a reference of assessment of technology clean. Finally, based on the theory of sustainable development evaluation of environmental benefits of cold recycling technology, results showed that technology cleanliness of cold recycling technology reflects the technology of sustainable development.Throughout the implementation of engineering and the technical and economic evaluation of cold recycling technology, it shows cold recycling technology can adapt to the requirements of development in Fuxin, saves economic expenditure, in line with the idea of developing green ecological sustainability in Fuxin. Therefore, it should be vigorously promoted in Fuxin, and definitely brings immeasurable economic and environmental benefits.
