Precast traffic barriers are concrete structures that prevent vehicles or pedestrians from entering vulnerable or unsafe areas or colliding with dangerous obstacles.
There are three common shapes of traffic barriers: Jersey, F-Shaped, and Constant Slope. Each of these meets durability and crash test standards.
The most common length of a traffic barrier is 10 feet. 20- and 30-foot variations may be better suited for some DOT applications that require greater permanence or stability.
Greater stability can be achieved by incorporating mat and bar reinforcement. Improved anchorage to prevent lateral movement can be addressed with interlocking joints and dowels.
