Title: ROADSIDE BARRIERS FOR BRIDGE-PIER PROTECTION
Accession Number: 00457489
Record Type: Component
Availability: Find a library where document is available Abstract: Seven full-scale crash tests were conducted to evaluate a concrete bridge-pier protection barrier. This barrier consists of four concrete half-section safety-shape barriers placed in front of the pier and flaring back from the pavement edge. The end of the concrete barrier is protected by a 6 by 6-in. box beam guiderail bolted to the concrete. The barrier was impacted at various points with either 1800- or 4500-lb sedans at 15 and 25 degrees and a speed of about 60 mph. The original design caused vehicles to roll over when the concrete barrier was impacted at 25 degrees near the first bridge pier. The design was modified by extending the box beam across the face of the barrier directly in front of the piers. This eliminated the rollover problem and strengthened the barrier, resulting in performance in compliance with the standards in NCHRP Report 230.
