Effect of Asphalt Oxidation on the Stability of Asphalt–sulfur Blends

Abstract

Oxidation by air blowing for different periods of time was used to modify the physical properties of asphalt. The effect of this treatment on the compatibility of asphalt with sulfur was studied using microscopic examination of more than oneyear aged samples. Improved compatibility of asphalt-sulfur blends was noticed with sulfur percentages of up to 15% by weight.
