Resumo: The tires discarded after use is one of the main environmental and public health problems of today, has a long time to decompose, constitute large volumes and function as water storage points, promoting the proliferation of vectors of diseases in humans. The tire retreading industry has been standing out on the world stage as one of the alternatives to minimize this environmental liability, prolonging the life of tires and acting as an alternative for reusing materials, however, the volume of waste generated in the process is still much environmentally questioned. In this sense, the present work aims to produce concrete with tire residues from the retreading process for application in drainage element (curb) partially replacing the kid's aggregate (5% and 7%) tire residues. Experimental procedures were performed as a physical characterization of the residues and materials that make up the concrete produced; axial compression and traction in flexion. The results show that the best composition to be used is with 5% of residues, because its resistance to axial compression (22.72 MPa) and traction in flexion (4.81 MPa) presented better results. Even so, all the compositions analyzed will decrease the mechanical resistances proportionally will decrease the amount of residual material contained in the concrete, such as the sample with 7% of the incorporation of tire residues that showed an improvement in tenacity to the Fracture. It can be concluded that the use of retreading residues for the production of prefabricated elements of non-structural concrete is technically and environmentally friendly, and other applications of this technology are possible in the production of similar parts.
