Trinity Attenuating Crash Cushion (TRACC)
Purpose: The TRACC is an end treatment for concrete barriers. It is limited to use in construction or other work zones on a temporary basis.
Description: The 21 foot long TRACC includes four major components: a pair of guidance tracks, an impact sled, intermediate steel frames, and 10 gauge W-beam fender panels.
Functionality: The sled (impact face) is positioned over the upstream end of the guidance tracks and contains a hardened steel blade that cuts the metal plates on the sides of the guidance tracks as it is forced backwards when hit head-on.
Foundation: The system requires a concrete foundation.
Slope: 10H:1V or flatter slope between the edge of the traveled way and the near face of the unit.
