FIELD: road building, particularly methods or arrangements for preventing slipperiness or protecting against influences of the weather.
SUBSTANCE: method involves providing double surface treatment, including treating ballast with bitumen, dispersing treated ballast in two layers over road and compacting thereof along with bitumen pouring over each ballast layer. Ballast made of main rock or slag ballast is used. Before ballast treatment with bitumen limestone or slag screenings in amount of 30-40% of ballast mass are added to the ballast. The obtained bitumen-mineral mix is dispersed in hot state and compacted.
EFFECT: improved quality and service life of pavement coating and simplified protective coating forming technology.
