ROAD BUILDING-DESTINED ORGANOMINERAL MIX Russian patent published in 2005 - IPC

FIELD: manufacture of road-building materials.

SUBSTANCE: invention relates to road and airdrome building field and can be used for building highway and airdrome bases. To that end, organomineral mix including 100 wt parts of mineral material, 12-20 wt parts of oil slime, 10-18 wt parts of and lime-containing component contains, more particularly, solid oil slime composed of, wt %: asphaltenes 1.5-4.0, resins 4.0-7.0, unsaturated hydrocarbons 6.0-10.0, paraffins 20.0-50.0, suspended impurities 40.0-60.0, and water 2.0-10.0; mineral material is composed of low-strength limestone crushing rejects or crushed sands, or mixtures of crushed sands with natural sands having grain size less than 5 mm; and lime-containing component is water-softening slime with chemical analysis, wt %: SiO₂ 5.44, TiO₂ 0.07, Al₂O₃ 1.48, Fe₂O₃ 5.73, MnO 0.08, CaO 42.5, MgO 4.29, Na₂O 0.11, K₂O 0.21, P₂O₅ 0.16, SO₃ 0.27, and other useful admixtures 39.6.

EFFECT: increased strength of material, reduced its cost, and enabled utilization of wastes from oil production industry and water-softening processes.
