Limitations and Warnings
Trinity Highway contracts with independent crash testing facilities to test and prepare crash test
reports for FHWA review.
The QuadGuard®Elite M10 has been deemed eligible for reimbursement by the FHWA as
meeting the requirements and guidelines of MASH. These tests evaluate product performance
defined by AASHTO involving lightweight cars (approx. 2420 lb. [1100 kg]) and full size pickup
trucks (approx. 5000 lb. [2270 kg]). A product can be certified for multiple Test Levels. The
QuadGuard®Elite M10 Wide is certified to the Test Level(s) as shown below:
Test Level 3: 62 mph [100 kph]
These AASHTO 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 MASH as approved by FHWA.
Trinity Highway expressly disclaims any warranty or liability for injury or damage to persons or
property resulting from any impact, collision or harmful contact with products, other vehicles, or
nearby hazards or objects by any vehicle, object or person, whether or not the products were
assembled in consultation with Trinity Highway or by third parties.
The QuadGuard®Elite M10 system 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 site
specifications. The customer should be careful to properly select, assemble, and maintain the
product. Careful evaluation of site layout, traffic speed/type, direction, and visibility are some of
the elements that require evaluation by the highway authority 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.

System Overview
The QuadGuard®Elite M10 is a potentially reusable, re-directive, non-gating crash cushion for
roadside features of 24” [610 mm] or less in width with use of an approved transition. It consists
of energy-absorbing high density polyethylene cylinders surrounded by a framework of Quad-
Beam Fender Panels.
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 QuadGuard®Elite M10 system utilizes two types of Cylinders in a “staged” configuration that
are designed and tested to address vehicles as defined by MASH for both lighter cars and heavier,
high center-of-gravity vehicles.
Impact Performance
The 8Bay QuadGuard®Elite M10 systems have successfully passed the requirements stipulated
in MASH, Test Level 3 tests with both the light car and pickup trucks at speeds of up to 62 mph
[100 kph] at redirection impact angles up to 25 degrees.
During head-on impact testing, within MASH criteria, the QuadGuard®Elite M10 has been shown
to telescope rearward to absorb the energy of impact. When impacted from the side, within the
applicable MASH criteria, it has been shown to redirect the vehicle back toward its original travel
path and away from the highway feature.
Warning: It is the sole responsibility of the project engineer and/or local highway
authority and its engineer to ensure that the QuadGuard®Elite M10 and delineation
used meet all federal, state, specifying agency, and local specifications.
Warning: It is the sole responsibility of the project engineer and/or local highway
authority and its engineer to ensure that the QuadGuard®Elite M10 meets all
appropriate MUTCD and local standards.

TrinityHighway.com 18 Revision C September 2021
Site Preparation/Foundation
A QuadGuard
®
Elite M10 should be assembled on an existing or freshly placed and cured
concrete foundation (4000 psi [28 MPa] minimum). Location and orientation of the concrete base
and attenuator must comply with project plans or as otherwise determined by the resident project
engineer.
Recommended dimension and reinforcement specifications for new concrete foundations are
provided in Trinity Highway Concrete Foundation drawing, supplied with the system. The system
may only be assembled on reinforced concrete roadway (minimum 6” [150 mm] thick). Assembly
cross-slope shall not exceed 8% and should not twist more than 2% over the length of the system;
the foundation surface shall have a light broom finish.
Caution: Accurate placement of all steel rebar is critical to avoid interference with
the concrete anchor bolts.
Warning: Location of the Backup in relation to nearby objects will affect the
operation of the attenuator. Upon impact, the Fender Panels telescope rearward
and extend beyond the rigid Backup as much as 25” [635 mm]. Position the Backup
so that the rear ends of the last Fender Panels are a minimum of 25” [635 mm]
forward of objects that would otherwise interfere with movement of the rearmost
Fender Panels. Failure to comply with this requirement is likely to result in system
performance which has not been crash tested pursuant to MASH criteria and may
also cause component damage which will necessitate maintenance or
replacement of the system.
Warning:
Ensure that there is proper site grading for the QuadGuard
®

Warning: It is the responsibility of the local DOT or appropriate highway authority
to ensure that this assembly conforms to the AASHTO Roadside Design Guide.
Warning: It is the responsibility of the installer to ensure that your assembly
procedure meets all appropriate Occupational Safety and Health Administration
(“OSHA”) and local standards.
Asphalt Installations
Systems with a Tension-Strut Backup may be temporarily installed in construction zones on
asphalt. Assemblies on Asphalt Concrete (“A.C.”) must provide a minimum of 3” [76 mm] layer
of asphalt over a minimum of 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” [200 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 (p. 20). Contact Trinity Highway
for a complete list of approved adhesives (p. 3).
Concrete Installations
For concrete installations, the QuadGuard®Elite M10 system should be installed only on an
existing or freshly placed and cured concrete base (4000 psi [28 MPa] 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.
Recommended dimension and reinforcement specifications for new concrete pads can be found
on the standard drawings.
The QuadGuard®Elite M10 may be installed on any of the following foundations using the
specified anchorage:
Foundation A: Reinforced Concrete Pad or Roadway
Foundation: 6” [152 mm] minimum depth P.C.C.
