FIELD: construction.
SUBSTANCE: method to strengthen an asphalt road surface with a carbon nanomaterial includes usage of an asphalt concrete mix containing crushed stone, crushed stone siftings, sand and oil bitumen of "БНД" 90/130 grade. Besides, the oil bitumen is modified by carbon nanotubes in the amount of 0.005% from the bitumen mass, and modification of the oil bitumen with carbon nanotubes is modified under ultrasonic effect.
EFFECT: increased strength and elasticity of a produced asphalt surface, higher water resistance, heat resistance and frost resistance and expansion of temperature range of its laying in the field of negative temperatures.
