The impact of dynamic effects filtration on the results of the comparative analysis performed with falling weight deflectometers

The paper evaluates the influence of dynamic effects filtration incorporating the method of deflection frequency normalisation on the results of the comparative analysis of falling weight deflectometer (FWD) dynamic instruments. The authors' calculations are based on a database comprising the results of comparative deflection tests conducted by use of six FWD instruments, on five different test sections, in strictly monitored on-site conditions. After analysing the results of deflection measurements subjected to the dynamic effects filtration procedure, it was possible to unambiguously determine the device for which the obtained deflection values differ most from the values obtained for other devices. The unequivocal selection of a device for comparative test results of FWD devices that had not been submitted to deflection frequency normalisation has not been possible. The calculations performed in the paper have confirmed the positive influence of dynamic effects filtration using the method of deflection frequency normalisation on the results of the comparative analysis of FWD devices.
