A method for the analysis of fatigue parameters has been rarely researched in VDT operation. Up to now, fatigue was evaluated by changing of biological information. If signals regarding fatigue are detected, fatigue can be measured. This study proposes an experiment and analysis method to extract parameters related to fatigue from the biological information(More)
A falling weight deflectometer (FWD) is commonly utilized to make structural evaluation of pavement systems, which applies impulsive force at a surface of pavement and measure surface deflections. Static back-calculation employs only peak force and peak deflections, while dynamic back calculation uses time histories of both. Since dynamic analysis of(More)
