Assessing Load Transfer Across Joints and Cracks in Rigid Pavements Using the Falling Weight Deflectometer
The report describes the evaluation of procedures for assessing the load transfer efficiency of transverse joints and cracks using FWD deflection data collected on a controlled jointed reinforced concrete pavement research facility in a laboratory study. The application of the procedures--on a number of jointed reinforced concrete pavement (JRCP) and continuously reinforced concrete pavement (CRCP) test sections on in-service rigid pavements, in order to determine their suitability for implementation in the field--is also discussed. The results presented indicate that the Falling Weight Deflectometer can indeed be used effectively to evaluate the load transfer efficiency of joints and cracks in rigid pavements and that the results from such evaluations can be used to establish maintenance and/or rehabilitation priorities. The procedures developed were also adapted for use in the evaluation of the efficiency for longitudinal joints in rigid pavements, particularly rigid shoulder joints. Again, the results presented show that with the FWD sensor configuration suggested, deflection measurements can be obtained for use in effectively evaluating the joint efficiency of the types of longitudinal joints found in rigid pavements.
