EVALUATION OF OVERLOADS ON PAVEMENTS FOR OVERSIZE/OVERWEIGHT PERMIT GUIDELINES

A rational test and evaluation procedure was developed to assess the load-carrying capability of flexible pavements (asphalt concrete surface over granular base/subbase) subjected to heavy loads from Oversize/Overweight Permit transport vehicles. A step-by-step method is described to evaluate pavements on designated Oversize/Overweight Permit routes, including the use of non-destructive falling weight deflectometer (FWD) deflection testing. The deflection test results are analyzed using a modified version of the PROBE software program to predict the pavement response (critical deflection) under the Oversize/Overweight Permit transport vehicle so that excessive deflection and ensuing pavement damage can be avoided. In addition, procedures are outlined to safeguard against localized and overall ground fracture under a single, and a large cluster of wheel loads, respectively.
