Development and validation of a temperature correction model for FWD backcalculated moduli
A temperature correction model for Falling Weight Deflectometer (FWD) backcalculated dynamic modulus was developed and validated in this study. FWD test was conducted to determine the field dynamic modulus, while the indirect tensile (IDT) dynamic modulus test was used to measure laboratory dynamic modulus. A temperature correction model was developed considering the effect of FWD loading frequency and pavement temperature. It was validated using field FWD data obtained from 26 Westrack pavement sections and Korean national highways’ long-term pavement performance database. Also, the correction factor was compared with similar existing models using FWD testing in the field. It was observed from study results that the temperature correction model is capable of predicting the dynamic modulus accurately.
