DEVELOPMENT OF FWD WITH WATER-BAG LOADING PLATE AND LINEAR ENCODER SENSOR

Although various Falling Weight Deflectometers (FWDs) have been developed, further improvement to raise the accuracy of existing FWDs should be made in two apsects. One is to develop a loading plate which is capable of applying uniform load constantly even if road surfaces are uneven. The other is to allow users to calibrate deflection sensors with ease. This paper describes the development of an FWD with a water-bag loading plate and a sensor which can measure the absolute displacement, to achieve the above two purposes.
