16. Abstract (Limit: 200 words)
In order to prevent vehicles from impacting bridge piers located in the medians of arterial roadways, roadside barriers
are warranted. For instances where roadside space is limited, rigid concrete barriers are often used to shield the bridge piers.
These concrete barriers need to be anchored so that they do not translate nor rotate during vehicle impacts. If the roadway
slabs do not extend far enough into the median in order to provide adequate anchorage, a footing may be required.
Therefore, a concrete barrier with a stand-alone concrete footing was designed, constructed, and crash tested.
The objective of the study was to evaluate the safety performance of an 813-mm (32-in.) tall, vertical concrete parapet
shielding a bridge pier according to the Test Level 3 (TL-3) criteria established by NCHRP Report No. 350. The barrier
width and reinforcement were optimized to provide adequate strength at minimal construction costs. A distance of 425 mm
(16.75 in.) between the barrier face and bridge pier was determined necessary to prevent critical vehicle snag. The footing
was designed to carry the barrier overturning moment during severe impacts, and thus maintaining the offset distance to the
front face of the bridge pier. One full-scale crash test was performed with a ¾-ton pickup truck. Following the successful
redirection of the pickup, the safety performance of the stand-alone, vertical concrete barrier was determined to be
acceptable according to the TL-3 evaluation criteria specified in NCHRP Report No. 350.
