ESTUDO DA SUBSTITUIÇÃO DO AGREGADO GRAÚDO POR PNEUS INSERVÍVEIS EM ELEMENTOS DE DRENAGEM

Abstract

With the increase of the vehicle fleet in Brazil and, consequently, the tire fabrication, it was observed the huge amount of tires on the market and the difficulties for their appropriate final disposal. Evidence of this fact is that nearly half of waste tires are co-processed, a technique that uses the material as partial fuel in kilns, causing harmful pollutants to be emitted on atmosphere. Stated this problem, it was realized the need to find a technique that could properly dispose large quantities of the material, being effectively environmentally friendly. For this purpose, the use of scrap tires on drainage layer in subsurface drains has been studied. In order to certify that it would be possible to employ this method, a technical, economic and environmental viable study was carried out, comparing the parameters of waste tires with the most commonly used drainage material, gravel. In addition, some works that used the proposed methodology and were successful were evaluated. In the end, it was concluded that scrap tires had good results and are perfectly applicable to some drainage systems, especially those where the material is not subjected to high all-around pressure
