Falling Weight Deflectometer for Nondestructive Evaluation of Rigid Pavements
The report presents an evaluation of the Model 8000 Falling Weight Deflectometer (FWD) manufactured by Dynatest as to variability and repeatability over a nominal range from 1,500 to 24,000 pounds and several rigid pavement structure. For the tests performed in the study the FWD exhibited statistically satisfactory values of variability and repeatability. Data are presented illustrating insitu moduli of rigid pavement layers using FWD deflection measurements. These values are compared to values generated by other devices. A procedure and criteria are presented for evaluating the load transfer efficiency of joints in rigid pavements and, for detecting the presence of voids under the surface layers.
