FIELD: road construction.
SUBSTANCE: invention relates to road construction, namely, to the composition of the modifying additive to the asphalt mixture, which can be used in the construction of pavements for roads and bridges in all climatic zones. The modifying additive to the asphalt concrete mixture is granules obtained from petroleum coke powder with a particle size of 60 - 90 microns and petroleum viscous road bitumen in the following ratio, parts by weight: petroleum coke powder 75-90, petroleum viscous road bitumen 10-25.
EFFECT: expanding the arsenal of modifying additives to the asphalt concrete mixture, increasing the stability of the surface layer of the road surface, its strength and slowing down the aging process.
