Abstract:

Growing efforts in the asphalt industry are focused on minimizing asphalt’s carbon footprint while extending the life of pavement through the introduction of a new generation of asphalt modifiers. This study evaluates asphalt mixtures containing low-carbon sulfur polymer modifier and reclaimed asphalt pavement (RAP) as a means to improving durability while reducing reliance on virgin materials. Low carbon sulfur-modified, RAP-rich mixtures were examined to understand if the modifier enhanced the strength properties of hot mix asphalt subjected to extended thermal and UV aging, conditions that simulate long-term real aging.
