摘要

Composition useful as a modifier for asphalt pavement, asphalt composition, and process of modification of the composition of asphalt. The present invention is a composition of asphalt modified with a polymer which comprises a mixture of elastomeric polymer, a plastu00f3mero with low molecular weight and a non modified asphalt.The compositions according to the present invention asphalt show greater elasticity and rigidity in comparison with compositions of asphalt modified with conventional polymers.
