System Overview TL-3

The REACT 350® Wide TL-3 can be mounted to a new or existing concrete backup. It can also be mounted in front of the hazard with a steel backup.

Design Criteria Special Site Conditions

Contact Trinity Highway Customer Service Department if you have questions about your application. Proper model selection is essential to the performance of the REACT 350® Wide. You will need to answer the following questions:

1. Are curbs, islands, or elevated objects (delineators or signs) present at the site? What height and width are they? All curbs and elevated objects should be removed. Curbs should be removed from behind the backup to approximately 50’ [15 m] in front of the REACT 350® Wide. Any curbs that must remain should be 4” [102 mm] maximum and be mountable. Signs should not interfere with the system’s ability to collapse. Generally, a vehicle should not interact with two appurtenances at the same time. Allow for adequate spacing.

2. If the deployment site is a gore area, place where two roads diverge, what is the angle of divergence?

3. What is the general geometry of the site? Include the roadway for 500’ [150 m] in front of the hazard, so traffic patterns can be visualized.

4. Is there an existing guardrail or median barrier at the site?

5. What is the width of the hazard to be protected?

6. Will there be traffic approaching from the rear of the system? Is the system in a two-way traffic situation with traffic going in opposite directions on either side of the system? Or, is the system on the side of the road where crossover traffic is a concern? If so, a transition from the hazard to the rear of the system may be necessary to prevent a vehicle from interacting on the rear of the system (p. 6).

7. Are there any other unique features at the site that may affect the positioning or performance of the REACT 350® Wide?

Other Factors That May Affect Your Assembly:

1. The existence of drain inlets or buried culvert pipe.

2. Junction boxes or other appurtenances located near the hazard.

3. Insufficient space for the length of system preferred.

4. The location and movement of expansion joints.

5. Breaking cross-slopes under or near the proposed assembly or severe cross-slope under the system. Provide leveling to 8% maximum slope (Figure 2). Often a system can be moved further forward to a more level site. Transitioning may be extended back to the existing hazard to accommodate the site.

Road Feature Width

The REACT 350® (60”) may protect obstacles up to 60” [1525 mm] wide.




Depending on site conditions, it may be necessary to provide a transition from the backup to the hazard.

Bidirectional Traffic

If bidirectional traffic (vehicles traveling opposite directions on either side of the system) is present, special consideration needs to be taken when placing the system. It is important that the backup itself does not become a hazard to the reverse direction traffic. If a system is placed in a location where traffic will be approaching from the rear of the system, the backup should not protrude beyond the hazard being shielded. Concrete transitioning may be required (Figure 3).

Warning: Impact conditions which differ from those described in the NCHRP Report 350 test matrix for non-gating re-directive crash cushions may result in different crash results than those encountered in testing. Furthermore, impacts in excess of TL-3 impact severity or the existence of unusual impact conditions such as vehicle instability resulting from traversing curbs or excessive cross-slopes prior to impact may compromise crash performance of the system. Performance criteria relative to structural adequacy, occupant risk, and vehicle trajectory may not meet NCHRP Report 350 evaluation criteria in those instances where the FHWA impact criteria are not met.
