FIELD: construction.
SUBSTANCE: invention relates to the field of construction road materials, namely to the asphalt-concrete mixture composition, which includes gravel, sand and modified petroleum road bitumen, which contains single-walled carbon nanotubes in the amount of 0.005–0.5 wt.% and on natural products and vegetable oils phosphatides based adhesion additive, or based on the fatty acids amidoamines and imidazolines, or based on the tallow oil with polyalkylamine compounds reaction products.
EFFECT: produced using this modified petroleum bitumen asphalt-concrete mixtures have the asphalt-concrete coating increased softening temperature and improved performance characteristics, which allows to use them for the highways, airfields, city streets and squares, and industrial enterprises roads coatings and bases construction.
