COMPOSITE RAW MIXTURE FOR MAKING ROAD PAVEMENTS Russian patent published in 2020 - IPC C04B28/04 C04B18/14 C04B111/20

Abstract RU 2712215 C1

FIELD: construction.

SUBSTANCE: invention relates to construction materials and can be used in road construction. Disclosed is a composite crude mixture for making road pavements, containing (in wt%): industrial waste metallurgical production – blast-furnace main granulated slag (46–49), an organomineral additive – a complex additive consisting of "Linamix PK" (1–3) and bitumen emulsion (4–6), and a silica-containing component – hydrofungus low-calcium brown coal ash TPP (44–47).

EFFECT: reduced porosity and increased strength and values of water resistance, hydraulic resistance and structural quality of the obtained material.
