摘要

FIELD: technological processes.;SUBSTANCE: invention relates to methods of cleaning ballast layer of railway track from contamination by oil products. Crushed ballast layer is placed in drum sink and supplied aqueous solution reagent destructor. For one hour, crushed rock is washed at 25–50 °C. Then, washing solution together with fine fractions of ballast is discharged into settler and separated into phases. Cleaned detergent solution is again supplied to a drum sink for cleaning of the next ballast load.;EFFECT: reduced toxicity of treated ballast.;3 cl
