Limitations and Warnings

Trinity Highway, in compliance with the NCHRP Report 350 “Recommended Procedures for the

Safety Performance of Highway Safety Features”, contracts with FHWA approved testing facilities

to perform crash tests, evaluation of tests, and submittal of results to the FHWA for review.

The REACT 350®II has been approved by FHWA as meeting the requirements and guidelines of

NCHRP Report 350. These tests typically evaluate product performance defined by NCHRP

Report 350 involving a range of vehicles on roadways, from lightweight cars (approx. 820 kg [1800

lb.]) to full size pickup trucks (approx. 2000 kg [4400 lb.]). A product can be certified for multiple

Test Levels. The REACT 350®II is certified to the Test Level(s) as shown below:

Test Level 3: 100 km/h [62 mph]

These FHWA directed tests are not intended to represent the performance of systems

when impacted by every vehicle type or every impact condition existing on the roadway.

This system is tested only to the test matrix criteria of NCHRP Report 350 as approved by

FHWA.

Trinity Highway neither represents nor warrants that the impact results of these federally

established test criteria prevent or reduce the severity of any injury to person(s) or damage to

property. These tests only demonstrate the occurrence of certain results following an impact

within NCHRP Report 350 criteria. Every departure from the roadway is a unique event.

The REACT 350®II is intended to be assembled, delineated, and maintained within specific state

and federal guidelines. It is important for the highway authority specifying the use of a highway

product to select the most appropriate product configuration for its site specifications. The

customer should be careful to properly select, assemble, and maintain the product. Careful

evaluation of the site lay out, vehicle population type; speed, traffic direction, and visibility are

some of the elements that require evaluation in the selection of a highway product. For example,

curbs could cause an untested effect on an impacting vehicle.

After an impact occurs, the debris from the impact should be removed from the area immediately

and the specified highway product should be evaluated and restored to its original specified

condition or replaced as the highway authority determines as soon as possible.

Warning: Do not assemble, maintain, or repair the REACT 350®II until you have

read this manual thoroughly and completely understand it. Ensure that all Danger,

Warning, Caution, and Important statements within the manual are completely

followed. Please call Trinity Highway at (888) 323-6374 if you do not understand

these instructions.

Warning: Only Trinity Highway parts that are specified herein can be used for

assembly, maintenance, or repair of the REACT 350®II. Do not utilize or

otherwise comingle parts from other Trinity Highway systems. Such

configurations have not been tested, nor have they been accepted for use.

Assembly, maintenance, or repairs using unspecified parts or accessories is

strictly prohibited.

TrinityHighway.com 6 Revision E November 2020

System Overview

The REACT 350®II is a potentially reusable, re-directive, non-gating crash cushion for roadside

obstacles up to 3’ [914 mm] wide.

Important: Trinity Highway makes no recommendation whether use or

reuse of any part of the system is appropriate or acceptable following an

impact. It is the sole responsibility of the project engineer and/or the local

highway authority and its engineers to make that determination. It is critical

that you inspect this product after assembly is complete to make certain that

the instructions provided in this manual have been strictly followed.

The REACT 350®II utilizes various Cylinder wall thicknesses to accommodate both light cars and

heavier, high-center-of-gravity vehicles.

The REACT 350®II consists of a series of “smart plastic” Cylinders attached to a steel Base Track.

The term “smart plastic” refers to the memory characteristics of the Cylinders. After a head-on

impact as described in NCHRP Report 350, the REACT 350®II has the potential to recover a

major portion of its shape, position, and energy absorbing capability. What constitutes a

potentially reusable highway product should only be determined by a trained engineer,

experienced in highway products, directed by the appropriate highway authority.

Two backup options are available to further meet specific requirements of each location. A Self-

Contained Backup is available or the REACT 350®II can be mounted to a new or existing

Concrete Backup. In some locations, either Backup type may be applicable.

AASHTO Roadside Design Guide, including, but not limited to, those regarding

placement on or adjacent to curbs.

Asphalt Installations

REACT 350®II systems with a Self-Contained Backup may be installed in construction zones on

asphalt. Assemblies on Asphalt Concrete (“A.C.”) must provide a minimum 3” [76 mm] layer of

asphalt over a minimum 3” [76 mm] layer of Portland Cement Concrete (“P.C.C.”), 6” [152 mm]

layer of asphalt over 6” [152 mm] layer of subbase, or 8” [203 mm] layer of asphalt with no

subbase.

Important: Only 18” [460 mm] threaded rods, utilizing Trinity Highway approved

adhesive, can be used with asphalt foundations. Contact Customer Service for a

complete list of approved adhesives (p. 3).

Concrete Installations

For concrete installations, the REACT 350®II should be installed only on an existing or freshly

placed and cured concrete base (28 MPa [4000 psi] minimum). Orientation of the concrete base

and the attenuator must comply with the project plans or as otherwise determined by the resident

project engineer or appropriate highway authority.

Trinity Highway Approved Adhesive Anchoring System

A Trinity Highway approved adhesive anchoring system is required to securely anchor crash

cushions. Each approved adhesive kit contains adhesive, studs, nuts, washers and instructions.

Both vertical and horizontal assemblies are possible using an approved adhesive anchoring

system.

Important: Follow adhesive manufacturer’s temperature storage requirements.

Anchor Assemblies

Note: Read all Trinity Highway approved adhesive instructions before starting.

1) Prepare the Concrete Foundation

Warning: Do not allow anchoring adhesive to contact skin or eyes. See material

safety data sheet supplied with adhesive kit for first-aid procedures. Use only in

well-ventilated area. Do not use near open flame.

Warning: It is the responsibility of the installer to maintain a safe work area

including the use of standard work zone safety equipment & PPE: gloves, safety-

toe shoes, and eye / ear protection.

The anchor bolts (studs) that anchor the REACT 350®II system Backup and/or Monorail

sections to the concrete foundation must be those shipped in the kit or of high strength steel

(Grade B7 or SAE-J429 Grade 5) tensile strength. These studs must be set in minimum 28

MPa [4000 psi] concrete. Allow the concrete to cure a minimum of seven days before applying

anchoring adhesive.

2) Drill Boreholes

Caution: It is the responsibility of the installer to consult OSHA silica

respiratory standard 29 CFR 1910.134 for debris removal from borehole(s)

and use Trinity Highway approved adhesive to achieve optimum tensile

strength. Do not use diamond drill bits for drilling boreholes.

Use the part that is to be anchored as a drilling template. Use a rotary hammer drill to drill the

boreholes 1/8” [3 mm] larger than the stud diameter to the recommended depth. See the

approved adhesive instructions provided with your kit. Check to ensure all boreholes are

drilled to the proper depth and aligned with the part to be anchored per table below.

Anchor Drilling Information

Anchor Size: Bit Size Drilling Depth Torque Medium

3/4”x 7 1/2" 22 mm [7/8”] 160 mm [6 1/4”] Manufacturer Spec Concrete

3/4”x 18" 22 mm [7/8”] 420 mm [16 3/4”] 15 N-m [10 ft-lb] Asphalt

Important: When mounting on asphalt, initial torque shall be as shown

above. Due to the properties of asphalt, anchors may loosen over time. For

this reason Trinity Highway recommends anchoring to asphalt only at

temporary locations. It is recommended to re-torque anchors in asphalt

every six months to the recommended torque specification.

TrinityHighway.com 9 Revision E November 2020

3) Clean the Boreholes

Blow the concrete dust from the borehole using oil-free compressed air. Thoroughly brush it

with a 7/8” diameter steel bristle tube brush and then blow it out again. If the borehole is wet,

completely flush it with water while brushing and then blow it clean to remove all water using

oil-free compressed air.

Note: Use of the Trinity Highway approved vacuum drilling equipment is authorized to replace

the blowing and brushing requirement of Step 3.

4) Apply Approved Adhesive

Fill the borehole 100% full.

Caution: Fill borehole 100% full so it is even with the pavement surface per

manufacturer’s instructions.

5) Add Nuts to Anchors

Thread the nut on until flush with the end of the stud (Figure 2).

6) Insert Anchors in Boreholes and Wait for Adhesive to Cure

Push the stud down through the part to be anchored and into the borehole.

Warning: Do not disturb or load the stud until the approved

adhesive material has fully cured (instructions supplied with

the approved adhesive kit).

7) Torque the Nuts

Once the adhesive has fully cured, torque the nut to the

manufacturer’s recommended values.

Anchor Assembly Cautions

1) Steel rebar

If steel rebar is encountered while drilling an anchor bolt borehole, apply one of the following

solutions:

A) Use a rebar drill bit for the rebar only and then switch back to the concrete bit to finish

drilling into the underlying concrete until the proper borehole depth is reached.

Caution: Do not drill through rebar without first obtaining permission to do so

from the project engineer.

B) Drill a new borehole down at an angle past the rebar to the proper depth. Anchor the stud

by completely filling both boreholes with an approved adhesive.
