Abstract
Structural evaluation of pavement structure is performed by static backcalculation using peak loading and deflections values. Backcalculated moduli reflect on various errors and their magnitudes have been reported. Dynamic backcalculation is more suitable than static backcalculation because FWD is an impulsive loading test.
However, effect of errors due to dynamic backcalculation has not been examined. This paper identifies the effects of modeling errors, measurement errors and lack in synchronization on backcalculated results. Dynamically backcalculated results are compared with statical results and difference in those results is examined.
