Description	Elemental sulfur is a material that is available in abundant quantities in its natural form as well as an industrial waste product. Sulfur is a viable alternative and sustainable binding agent that can be used as a construction material in large scale. One example is sulfur extended asphalt (SEA) that replaces approximately 30% of asphalt binder by weight in a typical asphalt mixture. Since the introduction of sulfur material in the 1970s, several different technologies for the use of SEA have been developed. A detailed review of these technologies can be found in the literature (Sakib et al. 2019). While most of the work was done in the 1970s–80s, Saudi Aramco has continued the investigating the use of elemental sulfur in pelletized form (to reduce dust and related problems) as a bitumen extender for the sulfur extended asphalt (SEA). In 2006, three roads in the Kingdom of Saudi Arabia (KSA) were built using this approach: Khuraniyah access road, Shedgum–Hofuf road, and Dhahran–Jubail expressway. These sections were evaluated after three years and found to be in satisfactory condition. The main goal of this paper is to present a summary of the materials design, evaluation, and construction practices as well as performance from three projects that utilized significant amounts of SEA in pavement construction in 2017: Wasea Bulk Plant, the Jizan Economic City Mega-Project, and the Fadhili Gas Plant Program. Although these sections have been in place for 2 years, it is important to highlight that these projects were access roads leading in and out of major plants, and therefore experienced a high volume of heavy traffic. Therefore, with the exception of the influence of long-term oxidative aging, these sections serve as an excellent indicator for the performance of SEA mixes.
