Resumo:
The highways allow the economic integration between the regions of the country
and provide great benefits to society, being one of the main transport systems
used for the displacement of people and goods. Therefore, it is important that this
infrastructure be maintained adequately and satisfactorily, so that the problems
related to it do not interfere in the operational costs of vehicles, nor raise the
prices of services and goods traded. Thus, this study had as main objective to
evaluate the physical properties of the modified asphaltic binder by addition of
lignin from pine. Softening point, viscosity and penetration tests were performed
for the lignin modified binder at 3%, 6% and 9%, before and after aging. It was
observed that the content of 3% of lignin gave a higher resistance and a tendency
to less wear with the aging, for the content of 6% of lignin it is recommended to
use for places with high temperature variations and, for the content of 9 % lignin
obtained satisfactory resistance results.
