Research of the technology for the production of modified sulfur bituminous binders

Abstract

In this article, a review of the literature on the technology for producing elemental sulfur-based paving material was reviewed, and a laboratory test of this technology was conducted at the Department of Highly Viscous Crude Oil and Bitumen. Natural. Attempts to mix sulfur with bitumen to reduce the cost of road construction and sulfur use were undertaken earlier, but the resulting blends did not provide the appropriate quality and the process was difficult to implement. The article proposes a unique technology to obtain not a physical mixture, but the formation of a chemical bond between sulfur and bitumen with the formation of bitumen polymers. This technology becomes possible with the use of a catalyst specially developed by the initiators of the project and has no equivalent in the world practice. And we add that the subject of the production of sulfur bitumen is not a question of actuality on the one hand since 1970, many researchers are interested in this subject but as with the abundance of oil and no one question about alternative solutions, and today with the reduction of traditional oil this theme is really soliciting.

Research on the effects of sulfur on characteristics of sulfur bituminous binder (SBB) and hot mix asphalt – sulfur (HMAS)

“…The rule of varying the penetration of SBB samples with different sulfur content over the days is explained by the crystallization of sulfur by the time [9,10,11]. The penetration of SBB decreased show that the stiffness of the SBB mixture was seen to increase with time.…”
