Abstract
Research is being conducted on potentially large-scale uses of sulfur to extend or replace such construction materials as asphalt, cement, and mineral aggregates. Paving materials have been developed in which sulfur replaces up to 50 pct of the asphalt and which can be handled with existing mixing and paving equipment. Studies involving the use of sulfur-asphalt mixtures as binders for good graded aggregates showed that the resulting materials were equal or superior to those in conventional bituminous pavement. Laboratory mix design studies and tests on mixtures containing poor- quality aggregates or graded sands demonstrated that sulfur in the binder upgraded the properties of the substandard aggregate and resulted in materials suitable for normal paving uses.
