Abstract
The paper describes the field experimental studies which were carried out on active sections of the railway track. The research observed the ballast layer using direct methods to determine the properties of the material and the deformation modulus by dynamic tests from the impact force action through a round stamp using the ZORN ZFG 3.0 device. As full-scale sections, hauls with varying contamination and missed tonnage were selected as well as a section of the cargo yard track where the ballast layer had not been cleaned for a long time. Based on the results of the studies, the links between the abrasions of crushed stone, the resistance of crushed stone to impact on a pile driver and the clogging of the ballast layer were determined. It was obtained the links between the clogging of the ballast layer and the deformation modulus.
