• Abstract:
  RMODS is a rigid pavement evaluation and backcalculation system developed by the Texas Transportation Institute for the Texas Department of Transportation. The system processes Falling Weight Deflectometer data to generate information on the structural strength of the concrete slab and the subsurface support. Outputs from the system include: a. the elastic modulus of each layer, b. the modulus of subgrade reaction (k) and characteristic length (IJ for center slab or edge loading, c. the load transfer efficiency of joints or cracks, and d. the presence of voids beneath joints.
