RESUMO:

Set in a scenario in which municipalities find it difficult in the treatment and disposal of all types of waste, the construction sector is presented with various problems, including the lack of disposal sites Waste Construction and Demolition - RCD, combined with high transport costs of these materials. Within this context, one way to minimize the problems relating to the disposal of RCD's is the reuse of this waste, resulting in reducing the volume of materials sent to landfills and environmental impacts generated by this provision, in addition to reducing the consumption of new materials. This paper presents the evaluation of the feasibility of substitution of raw materials for construction waste processed, based on life-cycle assessment of the material no longer used, in this case, the gravel pecks race, using the software "Umberto" . The material to be studied, the crushed stone waterspout race, would be used as floor subfloor, the works of enlargement of the Av. Dom Pedro I, in the city of Belo Horizonte, partly being replaced by waste generated and processed at the construction site. Using the software “Umberto” were raised all inputs and outputs of crushed stone waterspout busy life cycle of material and energy flows, allowing the integrated assessment of environmental and economic aspects of the material. Based on the calculated quantity in the records measurements and work projects, and the executed services, the analysis performed on the "Umberto" software has shown that the unit cost (m³) to perform sub-base paving using residues is about 23.79% of the cost of implementation using direct gravel waterspout running and the reuse of waste caused no longer be dumped into the environment over 21 tons of CO2, a large volume of N2 and CO in addition to saving 6,475 cubic meters of water. This amount of CO2 equals 134.43 trees, working over 20 years, or approximately 2,689 trees over a year. The volume of water saved would supply 10,792 people for 30 days.
