Abstract
Much effort has been made to verify backcalculated moduli based on deflections. However, pavement strain is of more interest to the pavement design engineer. A coparison of recorded strain at an instrumented road section with the strain obtained from backcalculation based on data from a falling weight deflectometer is presented. The agreement between the two methods is good, even if the backcalculated moduli show some discrepancy.
