Variability in Estimation of Structural Capacity of Existing Pavements from Falling Weight Deflectometer Data
As a result, the computed structural capacity becomes highly variable, especiallv when the number of test, done on a long; section of the pavement is smallI. The frequency of testing does not affect the estimated 18 kip ESAL over a short section of pavement. However, for long it affects the mean estimated 18-kip ESALs. For a mile long section five FWD tests were found to be a viahle choim h, r costimation of 18-kip ESALs. However, the coefficient uf variation of estimated 18-kip ESALs over a long section mav or m;w not decrease with increasing number of tests.
