FIELD: highway engineering, in particular paving upper layers building in all climatic regions.
SUBSTANCE: claimed bituminous concrete composition contains (mass %): lime chip of 5-20 mm fraction 35-45; petroleum viscous bitumen 5.0-5.5; mineral powder from dolomite or lime rocks 3-8; polymer additive 0.1-0.25 based on bitumen mass and balance: sand of 5 mm or less fraction. As said polymer additive polyethylene terephthalate in form of secondary plastic bottles is used.
EFFECT: bituminous concrete with improved structure-forming characteristics and increased water and heat resistance.
