Abstract Details

2010, Master of Science (MS), Ohio University, Civil Engineering (Engineering and Technology).
This thesis presents a model to predict the pavement response using Falling Weight Deflectometer (FWD) deflection data for asphalt concrete (AC) pavement. Evercalc 5.0 and Elmod 6.0 were chosen to conduct the backcalculation of pavement layer moduli using FWD deflections. Everstress 5.0 was used to do the forward calculation using backcalculated layer moduli. Predicted pavement responses (tensile strain at the bottom of the AC layer) were compared to the measured pavement responses from U.S. Route 30 to check the validity and accuracy of the selected prediction model. The predicted results show a good agreement with the measured responses. A comparison between FWD and truck load conditions was also conducted. The results show that FWD can accurately simulate the magnitude and the duration of a moving single wheel load.
