FIELD: road building materials.
SUBSTANCE: invention is related specifically to additives for asphalt mixtures, which are used in construction of transport infrastructure facilities in all climatic zones. A structuring additive for asphalt concrete mixtures is proposed, consisting of uncalcined petroleum coke containing particles finer than 2 mm (100%) and particles finer than 0.063 mm (at least 55%).
EFFECT: possibility of replacing the bituminous binder with a structuring additive in the production of asphalt concrete mixtures while simultaneously improving the performance of the resulting asphalt concrete, such as the water resistance coefficient and resistance to rutting without compromising crack resistance, as well as reducing the cost of manufacturing both asphalt concrete and structuring additive.
