Maintenance and Repair
The REACT 350
®
II, through crash testing, has been shown to be a potentially reusable crash
cushion. After impacts within NCHRP Report 350 criteria, it has been observed that, potentially,
the bulk of the system can be reused. However, whether or not a system is reusable is the sole
discretion of the highway authority specifying their use.
Warning:
Use only Trinity Highway parts on the REACT 350 ® II system for
assembly, maintenance, or repair.
The assembly or comingling of unauthorized
parts is strictly PROHIBITED.
The REACT 350 ® II and its component parts have
been accepted for state use by the FHWA. However, a comingled system has not
been accepted within the applicable criteria.
Important:
After impact, always follow Post Impact Instructions on page 36.
Estimated Time for Maintenance
An experienced two-person crew with the proper tools and spare parts should be able to complete
the work in one to three hours depending on the damage done to the system.
Life Expectancy
Impacts
Potential life expectancy of the system is mostly dependent on system impacts. This includes:
1. The number of impacts
2. The severity of the impacts
3. The temperature at the time of the impacts
The REACT 350
®
II must be inspected after each impact. Depending on the impact, components
may get damaged and need replacement. A cylinder requires replacement when the minor axis
of the cylinder stays permanently at 18” [460 mm] or less (Figure 29) or the system does not reach
90% of the original length. It is critical that all cables and anchoring be checked and returned to
original assembly conditions. Any parts used in the repair of the system must be original Trinity
Highway parts (p. 3).
