Limitations and Warnings
Pursuant to MASH “Recommended Procedures for the Safety Performance of Highway Safety
Features”, Valtir contracts with FHWA approved testing facilities to perform and evaluate crash
tests to prepare a crash test results report. Valtir is then able to submit a Request for Federal Aid
Reimbursement of Safety Hardware Devices to the FHWA for review.
The QuadGuard®M10 has been deemed eligible by 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®M10 is certified to the
Test Level(s) as shown below:
Test Level 3: 62 mph [100 kph]
Test Level 2: 44 mph [70 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.
Valtir 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 Valtir or by third parties.
The QuadGuard®M10 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.
Warning: Do not assemble, maintain, or repair the QuadGuard®M10 until you

Valtir.com 6 Revision F August 2022
System Overview
The QuadGuard®M10 is a re-directive, non-gating crash cushion for roadside features of
24” [610 mm] or greater in width with use of approved transitions. It consists of energy-absorbing
cartridges surrounded by a framework of Quad-Beam Fender Panels.
Important: Valtir 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®M10 utilizes two types of cartridges 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 six (6) Bay QuadGuard®M10 has successfully passed the requirements stipulated in MASH
with both the light car and pickup trucks at speeds of up to 62 mph [100 kph] at redirection angles
up to 25 degrees.
The three (3) Bay QuadGuard®M10 has successfully passed the requirements stipulated in
MASH with both the light car and pickup trucks at speeds of up to 44 mph [70 kph] at redirection
angles up to 25 degrees.
During head-on impact testing, within MASH criteria, the QuadGuard®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®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®M10 meets all
appropriate Manual on Uniform Traffic Control Devices (“MUTCD”) and local
standards.

Site Preparation/Foundation
A QuadGuard
®
M10, for permanent applications, should be assembled on an existing or freshly
placed and cured concrete base (28 MPa [4000 psi] minimum). Location and orientation of the
concrete base and attenuator must comply with project plans or as otherwise determined by the
local highway authority.
Recommended dimension and reinforcement specifications for new concrete foundations are
provided in Valtir concrete foundation drawings, supplied with the system. The system may be
assembled on a non-reinforced concrete roadway (minimum 8” [200 mm] thick). Deployment
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.
Warning:
It is the responsibility of the installer to ensure proper site grading for
the QuadGuard
®
M10
placement as dictated by the state or specifying agency
pursuant to the AASHTO Roadside Design Guide.
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 30” [760 mm]. Position the Backup
so that the rear ends of the last Fender Panels are a minimum of 30” [760 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.
Important:
Systems mounted on asphalt must be replaced and mounted on
fresh, undisturbed asphalt if more than 10% of anchors are found to be loose,
broken, or show signs of pull out. If 10% or fewer anchors are damaged, replace
the damaged anchors in the existing asphalt. Anchor bolts used on systems
mounted on asphalt must be inspected every 6 months. Review Maintenance and
Repair Instructions and Post-Impact Instructions (pp. 35-38).

Valtir.com 16 Revision F August 2022
Valtir Approved Adhesive Anchoring System
A Valtir approved adhesive anchoring system is required to securely anchor crash cushions. Each
approved adhesive kit contains adhesive, studs, nuts and washers. Both vertical and horizontal
assemblies are possible using an approved adhesive anchoring system.
Vertical Anchors
Note: Read all Valtir 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 QuadGuard®M10 Backup and/or Monorail sections
to the concrete foundation must be those shipped in the kit or of high strength steel (120,000
psi [830 MPa] minimum tensile strength or equal). These studs must be set in minimum
4000 psi [28 MPa] 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 Valtir approved adhesive to achieve optimum tensile strength. Do
not use diamond drill bits for drilling boreholes.
Use the Monorail(s) and Tension Strut Backup as drilling templates. Use a rotary hammer drill
to drill the boreholes 7/8” [22 mm] diameter to the recommended depth. See the approved
adhesive instructions provided with adhesive kit. Check ensure each borehole is drilled to the
proper depth and aligned with the part to be anchored per Anchoring Information table.

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 Valtir recommends anchoring to asphalt only at temporary
locations. It is recommended to re-torque anchors in asphalt every six (6)
months to the proper initial torque specified.

Valtir.com 17 Revision F August 2022
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 Valtir 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 the Washers and Nuts
Place a flat washer onto the stud then thread a nut on until the end of
the stud is flush with the nut (Figure 9).
6) Insert Studs in Boreholes and Wait for Adhesive to Cure
Push the stud down through the part to be anchored and into the
borehole.
Caution: Do not disturb or load the stud until the approved
adhesive material has fully cured (reference instructions
supplied with the approved adhesive kit).
7) Torque the Nuts
Once the adhesive has fully cured, torque the nut to the adhesive
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.

Horizontal Anchors
The horizontal approved adhesive kit is the same as the vertical kit.
Caution:
Fill borehole 100% full so it is even with the vertical concrete surface
per manufacturer’s instructions.
1) Follow the instructions supplied with your approved adhesive kit
