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.

“…The only defect of this method was the fainted copper color that can be symbolized with 3A4 on the Methuen color scale [11], although the color problem can be treated by raising the treatment temperature of sulfur to 400 C˚ according to the first patent [7]. This fact was confirmed again by another study conducted by Aldobouni et al [12] and Yin et al [13].which clarified the connection between the applied temperature and the remaining hydrocarbon in the crude sulfur with the quantity of liberated H 2 S gas (that indicates the speed of reaction), and the resulting color. However, unfortunately, these modifications were not conducted although the reason behind building industrial pilot plants is to…”
