Evaluating Structural Response of Flexible Pavement Based on Field Instrumentation
This study evaluates the structural responses for an eighteen-wheel vehicle in a flexible pavement with numerical analysis. The predicted stress and strains are compared with the field measured values. As a first step, a Finite Element Model (FEM) of the instrumented section is developed in commercial finite element software, ABAQUS. Stiffness of each layer is obtained by Falling Weight Deflectometer (FWD) test and backcalculated by ELMOD. The stress and the strain responses at some predefined locations are determined. Secondly, a total of 40 sensors are installed on Interstate 40 (I-40) at mile post 141 in New Mexico, to measure the stress-strain, loading configurations and environmental variations in the pavement. The outputs of the FEM are compared with the field measured values. Results show that the field responses closely match with the developed FEM model and thus, verify the numerical analysis.
