Field evaluation and analysis of flexible pavement structural responses under dynamic loads
Source abstract
Abstract
This study investigates the structural responses of flexible pavements at the Center for Pavement and Transportation Technology (CPATT) test track located at Waterloo, Ontario, Canada. A comprehensive field testing program was performed to examine flexible pavement responses to a variety of loading conditions. Tests were completed using six tire types: 11R22.5, 275/80R22.5, 295/75R22.5, and 285/70R22.5 dual tires, and 455/55R22.5 and 445/50R22.5 wide-base tires, and tire inflation pressures that ranged between 482 to 827 kPa. A two-dimensional finite element model was developed using MichPave software to predict pavement responses. A simplified method was proposed to characterize HMA properties using the laboratory dynamic modulus test. The developed model simulations approximated the field measured responses to all loading configurations.
