Structural health assessment of pavement sections in the southern central United States using FWD parameters

Various Departments of Transportation in the South-Central States and elsewhere have made extensive use Non-Destructive Testing (NDT) surface deflection bowl data. The falling weight deflectometer (FWD) test is a popular NDT-based used by transportation authorities to evaluate performance flexible pavement. Nevertheless, it rare develop method for evaluating pavement sections using FWD data from all sensors. There constant demand DOTs highway agencies streamlined approach that can be applied directly their databases. This research focuses on extending verifying concept previously published area ratio parameters section (Arkansas, Louisiana, New Mexico, Oklahoma, Texas) order properly analyze performance. Simulation-based deflections are employed strengthen deflection-based minimize need lengthy field testing. Ninety-seven these states being investigated implementation validation simplified processes will widely accessible different assess problems at network level.
