註釋The Surface Dynamics Profilometer, which has been used for several years by the Texas State Department of Highways and Public Transportation for road profile and roughness measurements, was recently updated to include non-contact or laser probes in place of the road following wheels. The upgrade also included a more up-to-date on-board computing capability. Likewise, procedures and enhancements to the Walker Roughness Device (WRD, or SIometer) was also recently completed. This current project was initiated to monitor the usage of this equipment, making any necessary improvements, etc., as the equipment was being used in actual field use. The report provides results of various applications of this equipment during the past year. The data were taken primarily by D-10 personnel.
