Measurement of the Magnitude of the Contact Area between Under Sleeper Pads and Ballast Bed Aggregates

Popis výsledku v původním jazyce

The article is focused on the issues of the magnitude of the contact area between the sleeper loading area and the ballast bed when under sleeper pads are applied. The application of under sleeper pads results in a change in the transfer of loads from the sleeper into the ballast bed. Under loading, the ballast bed aggregates are pushed into the elastic material of under sleeper pads increasing thus the area through which the load is transferred onto individual grains of the ballast bed. The article describes a new methodology of experimental investigation of the contact area between the under sleeper pad and aggregates applied in laboratory measurements and in-situ conditions. The objective of the measurement was the verification of the usability of this method and the determination of the contact area of selected types of under sleeper pads with different rigidity parameters. The aggregates used were both with sharp edged and round edged grains, in non-consolidated as well as consoli
