FIELD: highway engineering; laying upper layers of pavement in all climatic zones.
SUBSTANCE: proposed asphalt-concrete mix contains the following components, mass-%: sand, 10.0-22.0; mineral powder, 8.0-11.0; crushed stone screenings - fraction 0-5 mm, 64.5-72.0; viscous petroleum asphalt, 4.7-5.5; rubber modifying agent, 0.8-1.5. Rubber modifying agent contains rubber crumb, surfactant, polymer additive, sludge of chemical water treatment of thermoelectric plant and tar oil at ratio of from 26:2:12:12:48 to 39:1:8:8:44 mass-%.
EFFECT: increased strength parameters of asphalt-concrete mix at high water-resisting property; utilization of tire rubber.
