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 manufac turer’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

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.
