FIELD: chemistry.
SUBSTANCE: invention relates to production of road construction materials and can be used in repairing airfield and road surfaces, particularly for rapid and emergency restoration of damaged areas on asphalt pavements. A cold bitumen-mineral mixture, which contains mineral filler and binder, which includes bitumen, diesel fuel, tall oil and polyethylene polyamine, where the binder further includes fine wollastonite with particle size of 40-100 mcm, and the mineral filler used is any rock material with strength of not less than 60 MPa and grain size of 3-8 mm or 5-10 mm, with the following ratio of components, wt %: road bitumen 3.0-3.8, diesel fuel 0.8-1.3, tall oil 0.22-0.23, polyethylene polyamine 0.02-0.03, fine wollastonite 0.12-0.45, rock material - the balance.
EFFECT: high moisture resistance.
