FIELD: construction.
SUBSTANCE: invention relates to road construction, specifically to composition of activated mineral powder, and can be used in making macadam-mastic asphalt concrete mixture. Mineral powder for an asphalt-concrete mixture containing a homogeneous mixture of milled mineral component and a water repellent, in form of a mixture of a fat composition uniformly distributed on the surface of the mineral component, contains in the first version (MP-1) cement in following ratio of components, wt%: screening of limestone rocks crushing 95.83–95; water repellent 0.37–0.5; cement PC 500-DO of 3.8–4.5, and in second version (MP-2) – screening of limestone rocks crushing 96.08–95.3; water repellent 0.12–0.2; cement PC 500-DO 3.8–4.5.
EFFECT: technical result consists in improvement of swelling, porosity and mineral powder bitumen content index, expansion of used raw materials for its production.
