Resumo:
The construction of the extension of João Paulo II Avenue is an extremely important infrastructure project that seeks to promote mobility and improvement of road transportation to the metropolitan area of Belém. However, to guarantee the durability and quality of the paving work, it is necessary to application of constructive resources such as the use of different binders and granulometric bands in asphalt mixtures. As a consequence, the objective of the work is to evaluate the influence of the use of binder, with or without SBS polymer, and of the granulometric range, Range B or Range C, in the Marshall dosage parameters. For that, a statistical study was carried out using the box diagram, Student's t-test and linear correlation in the data obtained by the technological control of the pavement of John Paul II. The main results showed that the use of polymer influenced positively in the parameters RBV and negatively in the parameters RTCD, fluency, VAM and volume of voids. In relation to the granulometric range, when passing from Track B to Track C, there was a positive influence on the parameters stability and RBV and negative on the parameters fluency, VAM, void volume and apparent density. In addition, it was not possible to establish valid linear correlations between parameters the parameters (asphalt content, bulk density, void volume, VCB, VAM and RBV) and mechanical parameters (RTCD, stability and fluence) for most mixtures. Only the BsP blend (Band B, without polymer) showed valid linear correlations between bulk density, void volume, VAM and RBV versus RTCD and between asphalt content, bulk density and VAM versus stability.
