Abstract: The increase in levels of environmental pollution and generating residue is intrinsically
related to the contemporary life style, because there has been a growth in the consumption
of goods and services. To solve this problem, researches have been developed according to
the 3Rs: Reduction, Reutilization, and Recycling. This paper aims to develop a
minimization technology of the impact caused by the environmental passive, generated by
the scrap tires associated to support development. The tires have a singular physical
structure with great resistance and durability, even in the final of their useful life, being
inadequate to deposition in sanitary land-fillings because they do not allow compaction,
becoming favorable to the creation of disease vectors, besides offering great fire risks, with
serious environmental impact. The developed technology uses the rubber residue of the
scrap tires at the composition of low cost products to be used in the civil construction.
Mechanical process is used to divide the tire rubber into fractions to the attainment of
granulometric levels that allow the study of different rubber/bonding agent ratio, that are
pressed afterwards at several temperature levels. The bonding agent used was the
polyurethane resin derived from the castor oil (Ricinus communis) that is a renewed
resource, which also presents physical and chemical stabilities, and strong bonding
strength. The obtained composite was tested in compressive and tensile strengths, and had
determined its modulus of elasticity, showing satisfactory results to the application at the
civil construction as rubber pavements and filling sandwich wall materials.
