METHOD OF MAKING MINERAL-CONTAINING PAVING FOR FLOORS Russian patent published in 2013 - IPC C04B26/16 E01C7/30 

FIELD: chemistry.

SUBSTANCE: invention relates to construction and specifically to a method of making paving for streets, roads and other surfaces of transportation structures. The method of making paving for streets, roads and other surfaces of transportation structures, wherein a mixture is obtained, which contains a mineral material and a polyurethane reaction mixture, and optionally other additives, said mixture is applied onto a base material, pressed using pressure of at least 5 N/cm² and hardened, wherein treatment is carried out essentially without using solvents, and the polyurethane reaction mixture can be obtained by mixing: (a) isocyanates with (b) compounds which contain at least two hydrogen atoms which are active with respect to isocyanates, which contain a hydroxy-functional compound having hydrophobic groups, and optionally (c) chain elongation agents and/or polymer cross-linking agents, (d) catalysts and (e) common additives. Paving made using said method is also described.

EFFECT: obtaining paving which can be made and applied without polluting the environment, having high load bearing capacity and is not sensitive to ageing of the binding material.
