COMPARATIVE STUDIES OF DEFLECTOMETRY WITH BENKELMAN BEAM AND FWD SUPPORTED BY MECHANISTIC ANALYSIS AND REPEATED LOAD TESTING

Deflectometry of two road experiments in Brazil was made using both the Falling Weight Deflectometer (FWD) and the Benkelman Beam (BB). Deflection basins measured by these two instruments were compared to computed basins obtained through the finite element method and using resilient moduli results of repeated load testing. Measurements were made in different layers of pavement structures under construction. Noureldin's simplified procedure for backanalysis was used together with Benkelman Beam measurements.
