CRITICAL REVIEW OF THE SUITABILITY OF SULPHUR AS A COMPONENT IN VARIOUS CIVIL ENGINEERING APPLICATIONS

Sulphur Extended Asphalt (SEA) mixtures were used commercially in the 1970s and 1980s. Increases in sulphur prices, however, rendered SEA mixes uneconomical. Handling and safety issues also were of concern, as molten sulphur was difficult to use and occasionally generated H2S. Sulphur is a major waste of by-product from gas and oil production that has potential for encapsulation in civil engineering purposes mainly concentrating in road pavements.
