Absorb 350

The measured weight is per element. Nine elements are needed for TL-3 crash rating. This is a water filled attenuator that can be used to protect most temporary barriers. It should be used where gating is allowable and where a narrow attenuator is needed.

ADIEM

Can be placed on existing surfaces. Pinned anchorage allows unit to be moved and relocated quickly. BLON is 15 feet. Due to its heavy weight it is not easily transported to other locations. This attenuator should be used when gating is not desired.

Energite III System

Sand barrels that can be used to shield all types of temporary barriers. They come in various sizes and weights for the desired stopping power. These should only be used where gating is allowable. These barrels are filled with sand until the desired stopping power is reached.

The purpose of this site is to help plan Work Zones.

The basic idea is to present basic information about barriers and attentuators in a format that will allow quick comparisons in support of Work Zone planning. The primary sources of the information presented here are NCHRP 350 approval letters. The next steps in developing these pages are to improve the information presented and to review the presentation format. This will require practitioner input.
