Sleepers made of modified hardwood with high-quality impregnation significantly surpasses sleepers made of natural coniferous wood in their physical and mechanical characteristics. Obtaining such sleepers is possible by combining technological operations of pressing, drying and impregnation. In other words, all the time applying mechanical pressure, the wood is dried in a hydrophobic liquid with simultaneous impregnation. For the production of experimental batches of sleepers and the implementation of this method, a pilot plant SPK-1M was manufactured.
