Compressor

Features:

• Passed all required NCHRP 350 TL-3 Tests – FHWA Acceptance Letter HSSD/CC-95
• Compressor™ is a self-restoring attenuator designed to take repeated impacts with minimal or no repairs. After any impact, the system should be thoroughly inspected for damage or maintenance issues.
• Overall length: 21′ 3″ – Attenuator Module/Effective length: 16′ 6″
• Delivered assembled and ready to install – eliminated on-site assembly.
• Corrosion resistant solid steel Uni-Base™ requires only 14 bolts to secure compressor to the road.
• Compressor’s assembled design combined with the Uni-Base™ construction makes job site installation fast, easy, and safe – one crew can safely install several units in one day.
• Compressor’s specially formulated attenuator modules are injection molded from HDPE plastic and are designed to more efficiently absorb energy in a shorter distance.
• Attenuator modules are pre-flattened to provide more consistent results after repeated impacts.
• Compressor’s telescoping ultra high strength steel side panels re-direct side impacts with minimal damage to attenuator modules or panels.

Application:

In short, the TrafFix Devices Inc. Compressor is a re-directive, non-gating and self-restoring narrow crash cushion with a total length of 6.5 meters (255.25 inches). Its effective length is 4.98 meters (196 inches). The Compressor measures 1.24 meters (48.66 inches) wide, and is 1.36 meters (53.5 inches) in height. Its main components include: a steel mounting base, six plastic energy absorbing modules, and twelve steel fender panels.

Performance:

The Compressor Crash Cushion was originally accepted for use on the NHS for one-way traffic applications in FHWA Product Acceptance Letter CC-95 on February 26, 2007 and for two-way traffic applications in Acceptance Letter CC-95A, dated December 23, 2009. In both cases, the Compressor was mounted on a reinforced concrete pad using fourteen (14) anchor bolts for each of the crash tests conducted. For the present request, the Compressor itself remained unchanged from the previously accepted design.
