摘要：

This paper presents the analyses of the influence of different asphalt types on the mechanical properties of a dense asphalt mixture. Two penetration binders, CA 60/80 and CA 80/100, and styrene-butadiene-styrene (SBS) a modified polymer binder were used. Mechanical properties as cohesion, resilient modulus, indirect tensile resistance and rutting were evaluated. The results allow concluding that the mixture fabricated with polymer modified binder presents a better behaviour in the mechanical properties evaluated. Also, the compaction energy and test temperature have greater influence on the mechanical properties in mixtures fabricated with penetration binder than those done with polymer modified binder.
