Influence of Frost Protective Layers on the Realisation of the Track Bed Structure

Abstract

The railway track is a structure built of structural elements and materials with different material and geometrical properties. The design, construction, management and operation of the structure are governed by the standardized requirements of the railway infrastructure manager. The priority aspect of long-term serviceability is the resistance of the rail grid and the track bed to the stress. In terms of the railway body, the load is represented by the traffic and non-traffic load. The paper analyses various reference types of the track bed, (designed and assessed according to currently valid standards) and design types (designed, assessed and tested within the research of the Department of Railway Engineering and Track Management of the University of Žilina). Based on the parameters of the material and constructive structure, a matrix of activities of time plans for building reference and design models is created. This matrix also enabled to develop visualizations of standard links among construction activities.
