Using a Light Falling Weight Deflectometer for the Identification of the Sleeper Subsoil Layer Quality Degree in Railway Structures
Original language description
The paper presents the method of assessing the quality of a newly built sleeper subsoil layer. The method is based on using the light falling weight deflectometer (LFWD) dropped on a bearing plate and causing a deflection in the layer. The currently onlyapplied test for checking the quality of a layer used in the railway construction in the Czech Republic is the plate load test (PLT). It is a test both technically and time-consuming. One PLT for 200 m of track without a precisely specified place is prescribed for checking newly built sleeper subsoil layers on railway tracks in the Czech Republic. A complex assessment of the layer requires the identification of the worst place of the construction where PLT should be performed. For this purpose, the newly introduced term of the quality degree of the Zz layer obtained by means of LFWD is used. The layer quality degree is the ratio between the bearing plate?s deflection in the layer due to the first impact and an average impact obtained f
