FIELD: lubrication of heavily loaded friction units and mechanisms; more particularly lubrication of rails. SUBSTANCE: modified comprises, wt %: bitumen, 0.5-50; graphite, 0- 30; sand, 0-75; glass, 2-20; cement, 5-25; boric acid, 1-10; silicone composition, 3-40; and hydrocarbon solvent, the balance. EFFECT: widerange of variation of friction coefficient thus making it possible to use said lubricator for units which operate under high tractive forces. 1 tbl
