| Title of the article | Cast sulfuric concrete based on asphalt granulate |
| Abstract. | Problem statement. The aim of the work is the development of a cast road concrete mixture on the basis of asphalt-granulate for the construction and repair of road and airfield coatings. Results. On the basis of asphalt-granulate and mineral materials of sedimentary origin of deposits of the Republic of Tatarstan, cast non-shrinkage sulfur-concrete mixtures were obtained. It has been established that sulfuric concretes obtained as a result of self-compacting of sulfur-concrete mixtures have relatively high compressive and bending strengths of up to 20 and 12 MPa, respectively, and low water absorption, and the effect of plastification of mixtures is due to the surface interaction of asphalt granulate particles coated with asphalt with a melt of sulfur. During the hardening at the interface, a transition layer is formed, which increases the cohesive strength of the sulfur concrete structure. Conclusions. The significance of the results obtained for the road construction industry is to reduce the amount of direct financial costs for the production of asphalt and cement concrete, including the purchase of high-strength crushed stone from igneous rocks and the possibility of expanding the range of construction materials with new road-building mixtures. |
