What is sulphur asphalt (bitumen)?
Sulphur asphalt (SA), sometimes referred to as sulphur bitumen or sulphur extended asphalt (SEA), is a viable alternative for asphalt road binder, a process in which sulphur is used to extend asphalt materials as a means of energy conservation by minimizing asphalt demand. Combined with dried and heated stones and sand, either asphalt or SA can be used to make “hot mix” paving materials and build road. For more detailed information about sulphur asphalt and its use as construction materials worldwide, please see TSI’s Publications.
