• Abstract:
  The Federal Highway Administration has produced a Highway Performance Monitoring System Field Manual as a guideline for the individual states. The Field Manual includes an Appendix J which describes the proper calibration and reporting procedures for pavement roughness monitoring. The individual states are required to calibrate all roughness instrumentation and to report that roughness in terms of the International Roughness Index (IRI). This report details an evaluation effort sponsored by the Texas State Department of Highways and Public Transportation Maintenance and Operations Division, Pavement Management Section. This evaluation concentrates on the field performance of the auto-read version of the Face Dipstick. This instrument is one of the Class I profiling devices identified in the Appendix J mandate. All of the lower classification of roughness monitoring instruments used by the states must be calibrated against a class I device. The Dipstick was chosen by the Texas SDHPT because it was believed that the device would be a cost-effective and reliable substitute for the Rod and Level survey. Rod and Level and the IRRL Beam are the other two class I profiling devices specified by Appendix J. The evaluation effort describes concerns regarding the operation of the auto-read version of the Dipstick and the manufacturer's responses to those concerns. The field test sites utilized in the comparisons are described. 1be conclusions reached upon completion of the Dipstick evaluation are included. The manual-read version of the Dipstick was also included. The manual-read version of the Dipstick was also evaluated as to whether or not it would be a cost-effective class I profiling instrument. Finally, recommendations for the Dipstick's future use based on its field performance are described.
