ASPHALT AND CONCRETE MIX Russian patent published in 2022 - IPC C04B26/26 C08L95/00 E01C7/18 

FIELD: road building.

SUBSTANCE: invention relates to the production of road surfaces, in particular, to asphalt and concrete mixes used for creating the surface in the construction of automobile roads, aerodromes, sports fields in all climate types. The asphalt and concrete mix contains a bitumen-based binder and a mineral part represented by M1200 crushed stone of the 5 to 20 mm fraction, fine sand, MP-1 mineral powder, wherein the mix additionally contains ceramic granite crushing waste of the 0 to 5 mm fraction and a Bitaden 10 adhesive additive, with the following ratio of components, % wt.: bitumen 3.48 to 5.17, Bitaden 10 adhesive additive 0.01 to 0.02, crushed stone 37.1, mineral powder 7.6, sand 4.8, ceramic granite crushing waste 45.32 to 47.

EFFECT: increased resistance to mechanical deformations in a wide temperature range, high waterproofing capacity, reduction in costs due to the lowered amount of bitumen in the asphalt concrete mix and the use of ceramic granite waste, expanded base of raw materials while applying local man-made materials.
