​

Concrete Barrier Walls are more cost-effective than alternative types of barriers. Other barrier types must be replaced whenever an impact occurs (even low-energy impacts), because they may not perform properly in subsequent impacts. Considerable time and cost must be spent maintaining other barrier types, endangering motorists and workers during each repair.

SPECIFICATIONS

• The NCHRP 350 TL3 tested J-J Hooks Concrete Barrier is approved in 47 states territories and provinces.

• Greatly improved safety for workers in construction work zones

• Concrete highway barriers are the preferred temporary barrier

• Provide a high level of containment

• Relatively inexpensive compared to other barriers

• Can be free-standing, bolted, or pinned

• The F-Shape is more commonly used for permanent concrete barriers. However, a few states use this shape for portable concrete barriers and it is under consideration by several others.

The F-Shape is a later generation of the safety shape that is intended to further limit vehicle damage. The lower sloped face redirects vehicles under low-impact conditions. During moderate to severe impacts, some energy is dissipated when the vehicle is lifted off the pavement. The F-Shape reduces this lift, which promotes better vehicle stability while maintaining vehicle redirection. In crash tests, the F-Shape has proven to be more successful in preventing rollover of smaller vehicles. The F-Shape has been found to be more effective overall than the Jersey Shape barrier in some instances.
