Abstract:

This article reviewed the literature data on the technology of production of pavement material based on elemental sulfur, as well as the results of laboratory testing of this technology at the Department of High-viscosity oils and Natural bitumen. Attempts to mix sulfur with bitumen in order to reduce the cost of road construction and sulfur utilization were made earlier, but the resulting mixtures did not provide the appropriate quality, and the process was difficult to implement. The article proposes a unique technology for obtaining not a physical mixture, but the formation of a chemical bond of 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 analogues in world practice
