After the introduction of vehicle-based systems of road roughness measurement in the United States, a survey was made of such systems in Australia. The qualities sought were simplicity, trouble-free operation, and ability to predict the present serviceability rating of pavements (as determined by a panel of drivers). Two systems were selected for field trials: the PCA road meter and the Mays road meter. An apparatus was then developed that combines features of both meters. This apparatus and its operation are described in this paper. Development of improved methods of displaying, recording, and storing data as well as a method of obtaining a continuous trace of body-axle displacement is also described. Current use of roughness data in Australia and possible future applications are discussed. An area of concern common to all systems that are based on the measurement of body-axle displacement is the establishment of a standard against which vehicles can be periodically checked. Efforts made in Australia to overcome this problem are described. /Author/
