PRODUCT DESCRIPTION

New Hardware



INTENDED USE

The Retro-RailTM System has been crash tested and found to successfully meet MASH Test Level 3
impact criteria when properly attached to structurally-sound, “Strong-Post” Guardrail, with a rail
height of 25” to 29”, [Reference- 2009 American Association of State Highway and
Transportation Officials (AASHTO) Publication; Manual for Assessing Safety Hardware (MASH)].
Height is measured to the top of the rail from a horizontal tangent projected out from the top of an
adjacent roadway. The following types of Strong-Post Guardrail have been evaluated and are
deemed suitable for retrofitting with the Retro-RailTM System:

+ SGR04c - Steel Post/ Wood Blockout.

* SGR04b - Wood Post/ Wood Blockout.

* SGR04¢c - Steel Post/ Plastic or Composite Blockout (Similar to King Block®).

The Retro-RailTM System consists of two Cable End Brackets, a single 3/4” (19 mm) galvanized
wire rope running the length of the installation, and numerous Cable Mid Brackets supporting the
wire rope ~ 6” (152 mm) above the top of the rail. Cable Mid Brackets are installed every 12'-6”
(3,810 mm), using standard guardrail splice locations. The Cable End Brackets and Mid Brackets
maximize use of existing holes in the rail for attachment, minimizing the need to drill additional
holes.

A combined MASH Test Level 3 Guardrail & End Terminal system can be created by attaching one
of the above NCHRP 350 Retro-RailTM-fitted Strong-Post Guardrails immediately downstream
from a MASH, TL-3-accepted End Terminal.

APPROVALS
The Retro-RailTM System is compliant to MASH criteria for TL3 applications.
FHWA Eligibility Letter XXXX/B-XX, XX/XX/2013.

Evaluation Results

3-11 (2270P)

Four MASH 3-11 tests were successfully completed on the Retro-
RailTM System, Test 01-0289-001 and 01-0289-003 installations used
Steel Posts/ Routed Wood Blockouts on 6’-3” centers, 13’-6 %2" long
12 Ga W-Beam Guardrail with the top edge 25” above grade and
the Retro-RailTM System attached above and tensioned. Test
01-0289-001 impact occurred 48” downstream of Post #19, L/2.
This location was selected because it is believed to be “worst case”.
Impact would create the greatest snag potential between the post
and vehicle and create the greatest likelihood of W-Beam rupture.
Test 01-0289-003 impact occurred 12” downstream of post #3 to
establish system Beginning Length of Need (BLON). Tests
01-0289-005 and 01-0289-006 were conducted to further evaluate
Post/ Blockout combinations: Wood Post/ Blockout and Steel Post/
Composite Blockout respectively. To create the worst case scenario
for these Post and Blockout combinations, the impact occurred 48"
downstream of Post #19, L/2. This impact would create the greatest
snag potential between the post and vehicle and create the
greatest likelihood of W-Beam rupture.

PASS

3-20 (11000)

At this time the intended use of the Retro-RailTM System is not to
improve impact performance in transitioning from semi-rigid to
rigid barrier. Instead, replacement of this transition area may be
required to reach acceptable performance levels. The Retro-RailTM
System has been designed to attach to various Transition types and
heights.

|The Retro-RailTM System has been crash tested and found to successfully meet MASH Test Level 3 impact criteria
|when properly attached to structurally-sound, “Strong-Post” Guardrail, with a rail height of 25” to 29",
[Reference- 2009 American Association of State Highway and Transportation Officials (AASHTO) Publication;
Manual for Assessing Safety Hardware (MASH)]. Height is measured to the top of the rail from a horizontal
tangent projected out from the top of an adjacent roadway. The following types of Strong-Post Guardrail have

+ SGRO4c - Steel Post/ Wood Blockout.
+ SGRO4b - Wood Post/ Wood Blockout.
+ SGR04c - Steel Post/ Plastic or Composite Blockout (Similar to King Block®, width 105mm[4.0")
height 355mm [14.0°], depth 185mm [7.3"]).
The Retro-RailTM System consists of two Cable End Brackets, a single 3/4” (19 mm) galvanized wire rope running
ithe length of the installation, and numerous Cable Mid Brackets supporting the wire rope ~ 6” (152 mm) above
ithe top of the rail. Cable Mid Brackets are installed every 12'-6" (1,905 mm), using standard guardrail splice
locations. The Cable End Brackets and Mid Brackets maximize use of existing holes in the rail for attachment,
minimizing the need to drill additional holes.

|The Cable End Bracket consists of inner and outer galvanized components that “sandwich” a guardrail splice at
the termination points of the Retro-RailTM. The Cable End Brackets are designed to work with the rail to resist
normal and impact Retro-RailTM Cable tension. The top of the Cable End Brackets are fitted with a steel tube that
jaccommodates the threaded end of the Cable. The Cable End Bracket design is universal, allowing a single
Icomponent to be installed at either end of the system.

The Cable Mid Brackets incorporate an “engineered cable retention slot” intended to allow the Cable to float
freely within the bracket. During Guardrail impacts, the Bracket is designed to bend rearward, which facilitates
release of the Cable. This “release” transfers a significant portion of the impact vehicle's lateral impact energy
into the tensioned Retro-RailTM Cable. The Cable Mid Bracket is designed to maintain standard wire rope tension
when installed on guardrail with concave radii of 100’ or greater. If the Bracket experiences significant
longitudinal loading during impacts, it is desigried to bend and lay flat on top of the rail, reducing vehicle
snagging.

|The Cable is 3/4” 3 x 7 galvanized wire rope with threaded cable ends. It is pre-stretched at the factory. During
ithe Retro-RailTM installation, the Cable is tensioned to ~3500 pounds (dependent on the ambient temperature at
ithe time of the installation).

|A combined MASH Test Level 3 Guardrail & End Terminal system can be created by attaching one of the above
INCHRP 350 Retro-RailTM-fitted Strong-Post Guardrails immediately downstream from a MASH, TL-3-accepted
End Terminal.

Enclosures

Because it is a steel product, the Retro-RailTM, MASH is subject to Section 635.410
(Buy America) of Title 23, U.S. Code of Federal Regulations, and cannot be
permanently incorporated into any federally funded project unless it is made in the
USS. from U.S. steel.

Sincerely yours,

Michael S. Griffith
Director, Office of Safety Technologies
Office of Safety


Requirements

To be found eligible for Federal-aid funding, roadside safety devices should meet the crash test
and evaluation criteria contained in the American Association of State Highway and
Transportation Officials’ Manual for Assessing Safety Hardware (MASH).

Description
The device and supporting documentation are described in the attached form.

Summary and Standard Provisions

Therefore, the system described and detailed in the attached form is eligible for reimbursement
and may be installed under the range of conditions tested. Please note the following standard
provisions that apply to FHWA eligibility letters:

This letter provides a AASHTO/ARTBA/AGC Task Force 13 designator that should
be used for the purpose of the creation of a new and/or the update of existing Task
Force 13 drawing for posting on the on-line ‘Guide to Standardized Highway Barrier
Hardware’ currently referenced in AASHTO Roadside Design Guide.

This finding of eligibility does not cover other structural features of the systems, nor
conformity with the Manual on Uniform Traffic Control Devices.

Any changes that may influence system conformance with MASH will require a new
reimbursement eligibility letter.

Should the FHWA discover that the qualification testing was flawed, that in-service
performance reveals safety problems, or that the system is significantly different from
the version that was crash tested, we reserve the right to modify or revoke this letter.
