RESUMO

The polymer SBS - Styrene-Butadiene-Styrene has been very employed to modify the asphalt, for paving and for industrial applications. In that research the study of the asphalt was approached modified with polymer SBS, presenting better behavior than I asphalt conventional, being shown as the polymeric behaves when being mixed with the asphalt and which characteristics are gotten better. The asphalt modified with polymeric SBS it has an useful life very superior to the conventional asphalt, pointing out the drain pavements, that for your emptiness through where it drains the water it offers larger safety, durability, comfort, less costs with maintenance, time branch with trips faster, less stress, saved lives, and with all this to alert the government authorities and concessionary of highways that it is necessary to invest more with those materials of better quality, because in Europe and United States it is already applied a lot the asphalt modified with SBS. However it was also verified that nor all spaces of the highways can be used the drain pavements and which the pavements then that should be used in those spaces. It was also made a comparative one between costs and benefits of asphalts modified with polymeric and conventional asphalts
