FIELD: construction.
SUBSTANCE: invention relates to construction and can be used in pavement of automobile roads. Pavement includes a base - underlayer, layer of compacted sand, compacted crushed stone and a layer of hot coarse porous asphalt concrete, on which there is a coating of macadam-mastic asphalt concrete. Coating material used is macadam-mastic asphalt concrete with addition of fine grinding screenings of expanded clay with thickness of 40 mm.
EFFECT: reduced thickness of layers of road pavement, high strength, shear resistance, crack resistance and reduced flow of macadam-mastic mixture.
