Field Evaluation of Sulfur-Extended Asphalt Pavements

The term "sulfur-extended asphalt" (SEA), applied to a paving binder, paving mixture, or pavement, denotes the replacement of a significant portion of the conventionally used asphalt with elemental sulfur. Typically, 20 to 40 percent by weight of the asphalt is replaced with sulfur. The initial development of SEA technology was carried out
