The conducted researches of 40-70 mm fraction of crushed stone allowed receiving: – actual values of technical indices of the product and adopted technical decisions; – conformity of the product with the operating conditions as well as physical and mechanical properties during track maintenance; – ability to perform tests; – comparison of physical, mechanical and operational properties of crushed stone of 40-70 mm fraction with the crushed stone of 25-60 mm fraction.enrailway trackballast crushed stonecrushed stone of 40-70 mm fractioncrushed stone of 25-60 mm fractionoperating properties of crushed stonephysical and mechanical properties of crushed stoneКУПББМКККГArticle
