【 摘 要 】

This article discusses the issue of recycling of construction wastes during major repairs (rebuilding operations). The complete analysis of design and estimate documentation of the Russian Federation developed on the basis of the effectual statutory instruments allows us to draw the conclusion that the definition of usage of construction wastes usually includes the algorithm of their treatment (storage) with a purpose of transportation to the spoil disposal in the future. The investigation results are based on the on-site inspections of buildings where major repairs (rebuilding operations) are necessary, statistics, system analysis and analytical correlation of known practical and scientific facts. A policy of recycling of construction wastes during major repairs (rebuilding operations) was created, which includes 5 main phases: information acquisition, formation of set of technological combinations for every performance phase, comparison of handling abilities of the formed performance phase combinations, calculation of resource-saving exponent, calculation of energy performance exponent, choosing of the technology edition, formation of the construction wastes recycling system. Analytical dependences were found where the amount of construction wastes developing from demolition of defective and damaged sections depends on technical condition of a building carcass. Also, estimation criterion of method are offered: resource-saving and energy efficiency. During the implementation of recycling the resource-saving exponent ranges from 55, 22% to 88, 84%. In virtue of statistics it can be said without prejudice that even today the territory of the Russian Federation accumulates about 451 million tons of potential construction wastes rising from major repairs (rebuilding operations). In case of non-act all the mentioned capacity will exert downward pressure on the environment.
