FIELD: road construction.
SUBSTANCE: invention relates to stabilizing additives which are used in the preparation of stone-mastic asphalt concrete and can be used in the manufacture of road surfaces. Stabilizing additive contains an organic binder and a structure-forming agent. At that, as organic binder it contains construction bitumen BND 70/100 in amount of 20–25 wt.%, and as a structure-forming agent it contains mechanically activated petroleum coke in amount of 75–80 wt.%.
EFFECT: wider range of known agents, high resistance of stone-mastic asphalt concrete to stratification as per binder runoff, high resistance to rutting and low cost.
