THE EFFECT OF EDGE RESTRAINT ON FWD DEFLECTION VALUES TESTED ON ASPHALT ROAD PAVEMENT
This study investigates the effect of removing the road shoulder simulating a worst condition of the pavement edge. The study indicated a significant influence of edge restraint to the deflection readings. This effect gradually dimishes and becomes insignificant at a distance of about 2 meters from the edge. Deflection measurements using the FWD should take into account the edge restraint effect. It is recommended that the deflection variation across the pavement should be checked before conducting a deflection survey. The correct position of testing should be estimated to reduce the probable influence of edge restraint.
