Способ определения степени загрязнения балластного слоя железнодорожного пути, включающий отбор проб с последующим определением степени загрязнения, отличающийся тем, что отбор проб ведут без нарушения массива балластной призмы путем пропускания через нее сжатого воздуха, а степень загрязнения определяют путем измерения времени перепада давления сжатого воздуха.A method for determining the degree of contamination of the ballast layer of a railway track, including sampling with subsequent determination of the degree of contamination, characterized in that the sampling is carried out without violating the ballast array by passing compressed air through it, and the degree of contamination is determined by measuring the time of the differential pressure of compressed air.
