FHWA LTPP Guidelines For Measuring Bridge Approach Transitions Using Inertial Profilers

FOREWORD

This document presents guidelines to measure bridge approach transitions using inertial profilers. The guidelines were developed by the Long-Term Pavement Performance (LTPP) Program and the Office of Infrastructure Research and Development Bridge and Foundation Engineering Team. The bump at the end of the bridge has long been studied for highways and railways, yet experts from across the transportation industry continue to identify it as one of the most prevalent substructure factors affecting bridge performance. Often, rideability is a subjective measurement used by State transportation departments to define the presence of a bump. User complaints typically drive maintenance schedules. However, the bump is not just an annoyance on the traveling public; the dynamic impact of vehicles resulting from the bump causes distress, fatigue, and long-term damage to the bridge deck. In addition, the bump also causes damage to vehicles and potentially creates an unsafe condition for drivers when this issue is not maintained in a timely manner. This guideline describes the methodology for measuring bridge approach transitions using inertial profilers. Details include bridge sectioning and site information, data collection procedures, and data analysis and reporting approaches. The intended audience for this report is pavement and bridge engineering professionals and researchers.

The LTPP Program is an ongoing and active program. To obtain current information and to access other technical references, LTPP data users should visit the LTPP Web site at http://www.tfhrc.gov/pavement/ltpp/ltpp.htm. LTPP data requests, technical questions, and data user feedback can be submitted to LTPP customer service via e-mail at ltppinfo@fhwa.dot.gov.

16. Abstract

The bump at the end of the bridge has long been studied for highways and railways, yet experts from across the transportation industry continue to identify it as one of the most prevalent substructure factors affecting bridge performance. Often, rideability is a subjective measurement used by transportation departments to define the presence of a bump. User complaints typically drive maintenance schedules. However, the bump is not just an annoyance on the traveling public; the dynamic impact of vehicles resulting from the bump causes distress, fatigue, and long-term damage to the bridge deck. In addition, the bump also causes damage to vehicles and potentially creates an unsafe condition for drivers when this issue is not maintained in a timely manner. This guideline describes the methodology for measuring bridge approach transitions using inertial profilers. Details include bridge sectioning and site information, data collection procedures and data analysis, and reporting approaches.
