FIELD: road and airdrome building.
SUBSTANCE: invention relates to a road mixture that comprises mineral material, petroleum slag and bituminous sandstone wherein it comprises solid petroleum slag of the following composition, wt.-%: asphaltenes, 1.5-4.0; resins, 4.0-7.0; unsaturated hydrocarbons, 6.0-10.0; paraffins, 20.0-50.0; mechanical impurities, 40.0-60.0; water, 2.0-10.0, and also low-firm limestone crushing siftings with grains size less 5 mmn bituminous sandstone containing 7% of natural bitumen of the following composition, wt.-%: resins, 29.8; asphaltenes, 11.6; oils, 57.4; paraffins, 1.2 in the following ratio of components, mas. p. p.: mineral material, 25-75; solid petroleum slag, 8-12, and bituminous sandstone, 25-75. Proposed road mixture can be used in making pavement bases and cold-resistant earthy pavement layers, automobile roads and airdromes. Invention provides enhancing water resistance and resistance to cold of material, increasing exploitation period of road pavements, enhancing ecological safety of environment based on utilization of waste in petroleum extracting industry.
EFFECT: improved and valuable properties of road mixture.
