Estudo da aplicabilidade de borra oleosa asfáltica pura como material para pavimentos de baixo volume de tráfego

Abstract

The refineries are responsible for great part of the residues produced in the petroleum industry. Among the residues, an important one is the asphalt binder oil residue, accumulated in the bottom of the tanks, which is the object of this research. The present study aims to evaluate the use of the asphalt oil residue as a binder for asphalt layers used in low cost pavements, comparing the results with conventional asphalt binders used in hot asphalt mixes. Parameters of viscosity and temperatures were evaluated, as well as the mechanical behavior of the mixtures, using resilient modulus and indirect tensile strength tests. The results indicate the potential of this material to be used in asphalt pavements for low traffic roads, allowing an economic and environmental correct use of the residue.
