Sulfur asphaltconcreet

An influence of sulfur as a part of sulfur-bitumen binder on the properties of asphalt-concrete was studied. On the base of local mineral filling aggregates such as the bitumen of Achinsk oil-refiner plant and Norilsk combine technical sulfur, composition of road asphalt-concrete was calculated and prepared. Cakes-powder-like wastes of Krasnoyarsk «Krastzvetmet» plant were used as mineral powders. To compare the results asphalt-concrete mixture based on «pure» bitumen was prepared. The research conducted has shown that an introduction of sulfur into asphalt-concrete leads not only to the economy of bitumen, but to an increase in basic physical and mechanical properties. The composition of sulfur-asphalt-concrete is recommended for production. The main technological parameters of plant technology of sulfur-asphalt-concrete preparation and its application in road pavement are substantiated.
