The article describes a high-speed profilometer, developed by the Transport and Road Research Laboratory, for use on either new or existing roads. The profilometer and towing vehicle are designed to provide a self-contained system for the measurement and analysis of longitudinal road profiles at speeds of up to 80 kph. Data are obtained from four laser displacement transducers mounted on a 4.2 M rigid beam. A computer calculates average profile height over 107 mm sections every 107 mm. The profiles, once measured, are recorded onto a magnetic disc for subsequent analysis. An alternative program enables the sensor outputs to measure road surface texture. (TRRL)
