PRODUCT DESCRIPTION
New Hardware or Modification to
Significant Modification Existing Hardware

The SRT-MASH terminal became eligible via letter CC-100B dated December 5, 2012. With the publication of
MASH 2016, the test matrix for W-beam guardrail terminals was modified to include Test 3-37b. This test
involves an 1100C vehicle impacting the terminal at the critical impact point in the reverse direction at a speed
of 62 mph and an angle of 25 degrees. Additional testing was performed in accordance with MASH 2016 to
develop the SRT-MASH 2016 system.

The SRT-MASH 2016 terminal has a linear flare with a 4-ft offset over a length of 37.5 ft. The anchor post (post 1)
is a cable release post (CRP) embedded 6 ft-6 inches below grade. Steel yielding terminal posts (SYTPs) are
used for post 2 through post 10. The SYTPs are 6 ft long and embedded 40 inches below grade. Post 1 and post
2 are spaced 75 inches on center and connected at the ground line with a 3-inch x 3-inch x Y-inch angle strut.
The spacing between post 2 and post 3 is 56.25 inches. Post 3 through post 10 are spaced at 37.5 inches. The
last post spacing in the terminal between post 10 and post 11 (the first standard line post) is 56.25 inches.
Slotted 12 gauge W-beam rail is used in the first 25 ft of the SRT-MASH 2016 system. A single 3/4-inch x 13%2-
inch long slot is in the rail at post 1. Two sets of slots are located in the first 12 ft-6 inches of rail between post 1
and post 3. Each set of slots consists of three slots that are Y2-inch wide x 27-inches long. The next 12 ft-6
inches of rail contains two additional sets of slots located between post 4 and post 7. These sets of three slots
are Y2-inch wide x 12-inch long. Slot guards are bolted to the field side of the slotted rail at the downstream
end of each set of slots with the raised, narrow portion of the slot guard oriented towards post 1.

Posts 4 through 10 are offset from the rail using nominal 6-inch x 8-inch x 14-inch routed wood offset blocks.
No offset blocks are used on posts 1, 2 and 3. Posts 2 through 7 are not bolted to the slotted W-beam rail
panels. A shelf angle fabricated from '-inch steel plate is used at post 2 to provide vertical reaction for the
cable anchor system. W-beam flange protectors are used at posts 2 through 7 to provide additional vertical
support to the slotted W-beam rail sections. A cable anchor bracket is bolted to the slotted rail panel between
post 1 and post 2. A9%-inch long section of 1%-inch diameter schedule 40 pipe is positioned inside the cable
anchor bracket against the downstream bearing plate. The pipe insert positions the swaged fitting against the
end of the cable anchor bracket where it turns down to post 1.

The SRT-MASH 2016 incorporates a deflector bracket upstream of post 2 that is attached to the back of the W-
beam rail using four of the anchor bracket attachment bolts. This deflector bracket eliminates contact
between post 2 and the anchor cable assembly when the terminal is impacted in the reverse direction as in
Test 3-37b. The SRT-MASH 2016 also incorporates post 1 deflector plates on the downstream side of the
flanges of the post 1 stub. When the terminal is impacted in the reverse direction as in Test 3-37b, the post 1
deflector plates permit the undercarriage of the vehicle to slide up and across the post 1 stub after the release
of the top of the CRP post. This mitigates snagging potential between the vehicle and post 1 stub.

3-38 (1500A)

MASH 2016 Test Designation 3-38 is
designed to evaluate the performance of
staged energy-absorbing attenuators and
end terminals when impacted by a mid-size
vehicle. The SRT-MASH 2016 is not a staged
lenergy absorbing device. The slots of the
slotted rail sections buckle at a prescribed
level of force and is not dependent on
vehicle mass. Therefore, Test 3-38 is not
relevant.

Federal Highway
Administration

December 19, 2017 In Reply Refer To:

HSST-1/CC-140
Mr. Gregory A. Neece
Trinity Highway Products, LLC
2525 N. Stemmons Fwy
Dallas, TX 75204

Dear Mr. Neece:

This letter is in response to your October 17, 2017 request for the Federal Highway
Administration (FHWA) to review a roadside safety device, hardware, or system for eligibility
for reimbursement under the Federal-aid highway program. This FHWA letter of eligibility is
assigned FHWA control number CC-140 and is valid until a subsequent letter is issued by
FHWA that expressly references this device.

Decision

The following device is eligible within the length-of-need, with details provided in the form
which is attached as an integral part of this letter:
e Slotted Rail Terminal (SRT)-MASH 2016

Scope of this Letter

To be found eligible for Federal-aid funding, new roadside safety devices should meet the crash
test and evaluation criteria contained in the American Association of State Highway and
Transportation Officials’ (AASHTO) Manual for Assessing Safety Hardware (MASH).
However, the FHWA, the Department of Transportation, and the United States Government do
not regulate the manufacture of roadside safety devices. Eligibility for reimbursement under the
Federal-aid highway program does not establish approval, certification or endorsement of the
device for any particular purpose or use.

This letter is not a determination by the FHWA, the Department of Transportation, or the United
States Government that a vehicle crash involving the device will result in any particular
outcome, nor is it a guarantee of the in-service performance of this device. Proper
manufacturing, installation, and maintenance are required in order for this device to function as
tested.

This finding of eligibility is limited to the crashworthiness of the system and does not cover other
structural features, nor conformity with the Manual on Uniform Traffic Control Devices.

3-34,

[TTI Report No. 403371-SRT3, "MASH Test
3-35 on SRT-MASH."

[The 2270P, traveling at an impact speed of
62.4 mi/h, impacted the SRT-MASH 2016 6.8
inches downstream of post 4 at an impact
angle of 24.3 degrees. The SRT-MASH 2016
contained and redirected the 2270P vehicle.
|The vehicle did not penetrate or override
the installation. The SRT-MASH performed
acceptably according to the evaluation
criteria for MASH 2016 Test 3-35.

3-35 (2270P) PASS

MASH 2016 Test Designation 3-36 is
designed to examine the behavior of
terminals and redirective crash cushions
attached to a rigid barrier or backup
structure. As a W-beam guardrail terminal,
the SRT-MASH 2016 is not attached directly
to a stiff barrier or backup structure.
Therefore, Test 3-36 is not relevant.
