SULFUR-ASPHALT MIXING TECHNIQUE DEVELOPED

This article describes a new sulfur-asphalt mixing technique developed in Nevada. Molten sulfur is blended with regular asphalt before mixing with aggregate. The process is monitored with highly sensitive instruments which control weight amounts and temperature. The sulfur showed no discernible air pollution in the blending process or the subsequent roadway application. The sulfur-asphalt blend was first tried in the U.S. in 1975 in Texas where a half-mile road has been in use and is reportedly showing no deterioration. Other applications such as a concrete composed solely of sulfur and rock have been found to have great resistance to corrosive elements such as salt and acids.
