Abstract
The utilization of sulfur in sulfur-asphalt pavement materials is discussed from the standpoint of reducing asphalt demand in bituminous pavement systems. Two approaches for incorporating sulfur into asphalt aggregate mixes are (1) direct substitution and (2) the use of sulfur-asphalt emulsion binders. The relative merits of each approach are compared on the basis of standard physical and engineering properties of sulfur-asphalt blends and mixtures prepared with crushed limestone and volcanic aggregates. Correlations of laboratory data are made with field test results. The beneficial effects of using sulfur in the recycling of old asphalt pavement are also discussed.
