FIELD: construction.
SUBSTANCE: activated mineral powder comprises mineral agent made of carbonate rocks and mixture of oil bitumen and surface-active substances that are composed of a mixture of raw tall oil, distillated tall oil, tall pitch at mass ratio 1:(0.4-0.66):(0.6-1.66) and slate oil or residue pyrolysis wood resin that constitutes 0-50 mass percents of the mixture. The powder is composed of, mass %, 97-99.5 of mineral agent and 0.5-3 of mixture of oil bitumen and surface active substances, the mass ratio of bitumen to surface-active substances ranging from 1:0.5 to 1:3.1.
EFFECT: improved physico-mechanical characteristics of asphalt-concrete.
