FIELD: road building materials.
SUBSTANCE: invention relates to road building materials and can be used for the construction of various structural layers of pavement. The composition of the cement-asphalt concrete mixture for road construction purposes contains, wt.%: the mineral part in the form of granite crushed stone fr. 5-20 mm 48 and sand 41.5, binder - Portland cement 7.3-8.9 and acid fuel ash from the Troitskaya SDPP 1.6-3.2, bitumen emulsion (over 100% of the mineral part) 1, water (over 100% of the mineral part, excluding water present in the bitumen emulsion) 4.2, water-binding ratio 0.4. The invention is developed in the dependent claim.
EFFECT: preservation of the strength characteristics of cement-asphalt concrete when replacing part of the cement with acid ash.
