Guard Cable Systems (TL-3 & TL-4)

 

CASS TL-3 Guard Cable System

 

Time uses TL-3 and TL-4 Cable Barrier Systems, consisting of a 3-strand or 4-strand high tension median cable barrier, designed to contain and redirect errant vehicles from hazards.  Guard Cable barrier systems are a cost effective solution and are preferred by contractors for their ease of installation and its broad FHWA accepted applications.  There are several types of end treatments available as well, allowing us to fit your exact needs.

Full-scale vehicle crash/impact testing has been used to evaluate the safety performance of the TL-3 and TL-4 longitudinal cable barrier systems that Time offers.  All testing procedures were conducted as prescribed by the National Cooperative Highway Research Program (NCHRP) Report 350, Recommended Procedures for the Safety Performance Evaluation of Highway Features. The appraisal factors for evaluating crash test performance are structural adequacy, occupant risk and after-collision vehicle trajectory.  A test level is defined by impact conditions (speed, approach angle and vehicle type).
