CAST SULFUR CONCRETE MIXTURE Russian patent published in 2024 - IPC C04B28/34 C04B14/28 

FIELD: industry of road construction materials.

SUBSTANCE: invention can be used in construction and repair of highways and airfields as a structural layer of a base and a coating in a pavement structure. Cast sulfur-concrete mixture for arrangement of structural layers of coatings and bases of roads and airfields, it is characterized by that it contains sulfur, finely dispersed filler of ground mineral rocks of limestone or talc and asphalt granulate with particle size of 0.071–20 mm, with the following ratio of components, wt.%: said asphalt granulate 45.6–49.6, sulfur 32–37, said filler 15.7–22.4.

EFFECT: invention objective is to create a cast self-compacting sulfur concrete mixture, which does not require mechanized compaction means and tools when laying in a structural layer of a coating or base of a motor road or an aerodrome, with its subsequent hardening and production of finished structural layer of road pavement from sulfur concrete.
