| Resumo(s): | This paper describes the results of a study aiming the evaluation of pavement performance improvement by using a polymer modified bitumen as binder. Two dense graded bituminous mixtures were produced in laboratory. The first one was produced with conventional bitumen and the second one with polymer-modified bitumen. Permanent deformation tests were carried out in a shear servo-hydraulic machine using the repetitive simple shear test at constant height. Fatigue life tests were carried out in an axial servo-hydraulic testing system using a flexural beam. A comparison between these two mixtures was made for tensile strains calculated for a typical flexible pavement structure where these two mixtures were considered. |
