PROBLEMS ENCOUNTERED IN USING VEHICLE RIDE AS A CRITERION OF PAVEMENT ROUGHNESS

One criterion of pavement roughness has been the ride experienced in a passenger vehicle. This ride depends on the properties of the vehicle as well as those of the pavement. Recent changes in vehicle design (less weight and frontwheel drive) may affect this pavement criterion. To show the relationship between vehicle properties and ride, a simple mathematical model was selected for the vehicle. Vertical vehicle acceleration was used as a measure of the ride. For a pavement of known properties, the ride was determined for different speeds and different vehicle suspension characteristics. Significantly different values for the pavement criterion were obtained for the same section of pavement. It is believed that ride can still be used as a criterion of pavement roughness but that operating speeds and vehicle characteristics must also be considered in establishing this criterion. (Author)
