Descrição: AbstractIncreased environmental regulations and the rising costs of asphalt binder have encouraged researchers to investigate alternative binders that can be used for hot mix asphalt (HMA). This study focused on using bioasphalt as a possible alternative binder to petroleum-based asphalt. To evaluate bioasphalt as a HMA binder, both binder and mixture tests were performed. Bioasphalt was blended with traditional binders at different percentages (0, 10, 30, and 60%) by weight of the base binder. Binder test results, based on constant shear loading tests and multiple stress creep and recovery tests, showed that the addition of bioasphalt decreased the resistance to fatigue and rutting. The HMA mixture performance tests indicated that the addition of bioasphalt to the mix reduced the stiffness of the mix (dynamic modulus) and its resistance to rutting and fatigue cracking, but increased the resistance to thermal cracking. The moisture susceptibility test shows that bioasphalt mixes passed the minimum tensile strength ratio requirement.
