TWO METHODS OF MEASURING DYNAMIC PAVEMENT LOADING

TWO ON-THE-VEHICLE METHODS OF MEASURING THE DYNAMIC TIRE/ROAD INTERFACE FORCES OF HEAVY HIGHWAY VEHICLES HAVE BEEN DEVELOPED, AS WELL AS A METHOD OF PREDICTING THESE LOADS USING AN ANALOG COMPUTER SIMULATION. THE MEASUREMENT TECHNIQUES WERE USED TO RECORD DYNAMIC LOAD DATA FOR THREE VEHICLES TRAVELING ON PUBLIC HIGHWAYS. THE ANALOG SIMULATION WAS USED TO STUDY THE INFLUENCE OF VARIOUS VEHICLE CHARACTERISTICS ON DYNAMIC LOADS. THE ON-BOARD METHODS SHOWED, FOR EXAMPLE, THAT RIM INSTALLATION AFFECTS THE TIRE/ROAD INTERFACE FORCE. PEAK LOADS CAUSED BY PUBLIC HIGHWAY SURFACE IRREGULARITIES MAY BE AS MUCH AS TWICE STATIC LOADS. WITH THE ANALOG SIMULATION TIRES STIFFNESS AND ENVELOPING WERE COMPUTED TO HAVE A SIGNIFICANT EFFECT ON PEAK DYNAMIC LOADS. /AUTHOR/
