Testing and Evaluation of the Florida Jersey Safety Shaped Bridge Rail

D. C. Alberson / W. F. Williams / W. L. Menges / R. R. Haug

The objectives of this portion of the project were to: (1) determine if any or all of the three subject variants of the 32-inch (813 mm) Jersey safety shaped bridge comply with the requirements of the AASHTO LRFD Bridge Design Specifications and National Cooperative Highway Research Program (NCHRP) Report 350 Test Level 4 (TL-4), and (2) provide recommended retrofit schemes, if deemed technically and economically feasible, to bring into compliance the railings that do not comply. Full or partial replacement schemes may also be recommended as appropriate. The most direct approach for accomplishing the objectives of this task was to perform a full-scale crash test of the most critical design. If that railing performed satisfactorily, the railing would be acceptable by AASHTO LRFD Specifications. According to the results of this project, no field retrofits or replacements of the Florida Jersey safety shaped bridge rails, depicted in the Florida DOT Index 799, are warranted since the most critical 32-inch (813 mm) Jersey safety shaped bridge railing complied with the requirements of the AASHTO LRFD Bridge Design Specifications and NCHRP Report 350 Test Levels 3 and 4.
