Abstract

[Abstract]: A readily available and sustainable biomass resource that could be used as a bi-tumen extender or modifier is the biopolymer lignin. Nevertheless, there isn’t much agreement regarding how well lignin-based bituminous mixtures crack. The fracture performance of half-warm mix recycled asphalt (HWMRA), made with 100% reclaimed asphalt pavement (RAP) and 5% lignin-rich industrial waste in place of bitumen emulsion, was examined in the current research in this regard. The Fénix test was carried out with this goal in mind. The results were compared to those obtained for a control mixture (HWMRA with 0% of lignin rich industrial waste). At 20ºC the results were slightly better for the control mixture. But at -5ºC and 5ºC the results were similar for both mixtures. Therefore, it can be concluded that replacing 5% of the bitumen emulsion with lignin-rich industrial waste will not be detrimental to the cracking performance of half-warm mix recycled asphalt.
