The Development of a High Performance Material for a Ballast Layer of a Railway Track

A ballast layer – an element of the railway superstructure – ensures its vertical and horizontal stability under the effect of train loads and changing temperatures. Crushed aggregate is used as a base material for a ballast layer according to the standard technical documentation. The purpose of the study is to improve ballast layer operational characteristics, to prevent the ballast from incrustation and moisture, to eliminate stones rolling out from a ballast bed and to reduce track maintenance works. In order to solve these problems the authors propose a high performance polymer cement material modified by organic mineral composition containing nanoparticles [4]. The developed material is characterized by higher elasticity and crack resistance. It does not lose its properties under train loads. Besides it is resistant to chemical materials (oils, lubricants, acids) and is not failed when it is used in a temperature range from +50 °C to –60 °C.
