THE DETERMINATION OF SOFT SUBGRADE MODULUS FOR AIRPORT PAVEMENT REHABILITATION VIA BACKCALCULATION OF FALLING WEIGHT DEFLECTOMETER

The integrity of existing highway and airfield pavement is increasingly being evaluated based on the analysis of falling weight deflectometer (FWD) deflection basin data. This paper presents a detailed investigation of soft subgrade moduli via backcalculation from FWD data, triaxial testing, and pressuremeter testing. FWD testing was conducted and data was collected at more than 80 locations along a 1200 m general aviation flexible runway pavement.
