Evaluation of Pavement Deflection Measuring Equipment
A side-by-side test program was performed over a broad range of pavement structures, including thick and thin flexible and rigid pavements, and composite pavements. The measured deflections were compared statistically. Mechanistic interpretations of the measured deflection basins were made and compared. The report concludes that, based on the interpretation of field data, all devices gave comparable results on the tested pavements, except the Curviameter which gives invalid results on rigid and composite pavements. In addition, the Benkelman Beam and Curviameter exhibited much larger variability in comparison with the other devices.
