• Abstract:
  This report describes the methods and procedures for upgrading the Surface Dynamics Profilometer owned by the Texas State Department of Highways and Public Transportation. The upgrade performed included the installation of non-contact laser probes used in the process of measuring road profile. The laser probes make the Profilometer more useful for data collection by reducing maintenance problems occurring with the mechanical road-following wheels. The use of non-contact probes in the profilometer is also safer for data collection personnel as greater highway speeds can be used in the measuring process. The data acquisition and processing capability of the profilometer was also upgraded to reflect more up-to-date technology.
