Approved Temporary Barrier
Refer to Standard Construction Drawings RM-4.1 and RM-4.2 for generic Portable Concrete Barrier.
Any barrier (proprietary or generic) that is not Report 350 compliant was subject to a phase out period and was to be removed from service by January 1, 2008. ODOT required marking all compliant generic barrier with "350". This office will not accept NCHRP 350 barriers from other states for use on ODOT projects. These other products have different shapes (F or NJ), cross section (widths), or connection types. When intermingled with ODOT's standard barrier, potential snag points are created when an impacting vehicle travels from one segment to a dissimilar adjacent segment.
The following products may be used as an equivalent to ODOT's Generic Portable Concrete Barrier.
J-J Hooks PCB
The NJ Shape Portable Concrete Barrier with J-J Hooks is a proprietary "equivalent" to ODOT's generic NJ shape PCB. The J-J Hooks product is a proprietary barrier manufactured to Easi-Set's specifications. J-J Hooks barrier meets NCHRP Report 350 TL-3 criteria if manufactured with a third rebar (sometime after April 1999). Baxter Precast Products and Norwalk Concrete Industries stamped "350" on all complying J-J Hook barriers as well. It is not known how J-J Hooks barriers manufactured by out-of-state licensees identified compliant segments. J-J Hooks website
Zoneguard Steel Traffic Barrier
Zoneguard barrier is an approved alternate to PCB. Additional product information is available at Hill and Smith, Inc.
Standard Installation Drawing - ends only of entire runs are anchored for deflection comparable to PCB
Minimum Deflection Drawing - Each barrier segment is anchored for drop-offs or zero deflection.
Vulcan Barrier - portable steel longitudinal barrier
Vulcan Barrier Installation Manual (with ODOT markups)
- ODOT requires the ends of the Vulcan Barrier to be anchored in order to maintain acceptable deflection limits
- Ends must be shielded or terminated with an approved end treatment
- ODOT Length of Need requirements are calculated by designers per the Location and Design Manual Vol. 1 Figure 602-1
- Triton is not an ODOT approved end treatment
Quickchange Barrier, from Barrier Systems, Inc. uses a specially designed vehicle to move barrier runs upwards of 26 feet laterally, opening traffic lanes in a matter of minutes. It is a good product for reducing delays from lane closures in long duration work zones, and in permanent situations where there are high directional traffic volumes.
This movable barrier uses Barrier System's ABSORB 350
as its crashworthy end treatment. The ABSORB 350 system is a non-redirective, gating crash cushion that can be used with the Quickchange Barrier
Temporary Narrow Barrier
A generic tied-down steel barrier developed by the Iowa DOT that may be assembled in the field with 20 ft long stacked steel H-Beams filled with concrete. NCHRP 350 TL-3. Intended for use where cross sectional space is at a minimum. Deflection is 12 inches. Temporary Narrow Barrier.pdf
