Aproveitamento de resíduos sólidos de construção civil para pavimentação urbana : estudo de caso : pavimentação do Bairro Renascer, em Cuiabá/MT

Abstract

The construction and demolition waste are generated in large quantities in the cities, mainly due to demolitions, causing problems to the environment and the population disorders. However, for thousands of miles off-road in the city of Cuiabá, being studied in this work the Bairro Renascer, recycled household solid waste is a construction material that can be used for paving. This graduate work analyzes the mechanical properties of recycled aggregate employment in the pavement structure in particular the base and sub - base. The research consists of field visit in case the Bairro Renascer for sample collection and laboratory testing. The characterization of the subgrade was taken in Nortelândia Street, which is one of the main streets of the studied district, which has a stretch of 600 meters in length. The deck has scaled recycled aggregate in its structure, is presented in three different sections - type, evaluating the materials, thicknesses and compaction. Mechanical and physical properties of aggregates were determined in the laboratory by means of the following tests: particle size, plasticity index, density, intermediate compaction and California bearing ratio. The results showed that similar to crushed stone mechanical behavior and mechanical performance satisfactory, being approved for use on pavement base in NBR 15115 (ABNT, 2004) and DNIT 141 (DNIT, 2010) standards.
