Utilização de resíduos de vidros planos como fíler em misturas asfálticas - propriedades físico-químicas e mecânicas.

Abstract

Technological development has resulted in the generation of industrial waste and the scarcity of raw materials. One of the viable and applied solutions worldwide to minimize waste generation is its use of waste in the production chain, saving the use of conventional materials and minimizing the volume of waste dumped in the city's landfills and landfills. Glass shards are products considered to be 100% recyclable, but the flat glass category is not used for this purpose, as it may induce the appearance of cracks in the recycled object. For this reason tons of glass are thrown daily on wasteland and dumps. Vane waste, in addition to volume and shortening the life of the site, can cause injury to people who are coming to landfills and landfills, making it a gateway to microorganisms present in the remainder of the existing waste. One of the ways found for the use of flat glass residue was its use as a filler in asphalt mixtures. The characterization of the residue proved that it is a predominantly silica material, which makes it electrically neutral, with a high melting point, high viscosity, and produces materials with high mechanical resistance. By conducting the Marshall test and the diametral traction test by indirect understanding, the performance of the vitreous residue as a filler was evaluated as satisfactory, since the results of the observed parameters meet the recommendations imposed by the norms of the National Department of Infrastructure and Transportation - DNIT. the results presented by the Lottman test showed good tensile strength ratio results, being above the minimum value of 0.80 recommended by the Superior Performing Asphalt Pavements - SUPERPAVE. The resilience modulus test proved the results obtained in the other tests.
