FIELD: highway engineering; automobile road pavements.
SUBSTANCE: proposed asphalt-concrete mix contains bitumen, Grade БНД 60/90, slag of electric furnace steelmaking process, fraction 5-15 mm and additionally it contains stabilizing additive VIATOR 66, filler in form of screenings of slag of electric furnace steelmaking process, fraction 0-5 mm and mineral powder obtained after crushing the slag of electric furnace steelmaking process, fraction 0.071-0.14 mm at mass ratio of screenings to mineral powder of 0.94:1.02 at the following ratio of components, mass-%: slag of electric furnace steelmaking process, 63.07-71.48; screenings of slag of electric furnace steelmaking process, 15.46-11.02; powder after crushing the slag of electric furnace steelmaking process, 15.18-11.68; bitumen, 5.9-5.46; stabilizing additive VIATOR 66, 0.39-0.36.
EFFECT: improved technical characteristics of asphalt-concrete mix and consequently improved quality of pavement and its service life; low cost of mix due to utilization of waste of electric furnace steelmaking process.
