Abstract

Sulfur is an abundant co-product of the oil and gas production. By 2020, new regulations limiting the sulfur content in maritime fuels will increase its supply. There is a need to revisit cracking characteristics of sulfur modified asphalt concrete (AC) mixtures. The objective of this study is to evaluate the cracking resistance of sulfur extended asphalt (SEA) mixtures as compared to AC prepared with standard binders. One conventional AC and two SEA mixtures were prepared in the laboratory containing 0%, 15%, and 30% sulfur replacement by weight of the binder, respectively. The sulfur was added during the mix production in the form of pellets to mimic the procedures that can be used during plant production. The Illinois flexibility index test was used to assess the cracking susceptibility of SEA mixtures. Results obtained indicate decreasing cracking resistance with increase in sulfur addition.
