Dear Mr. Stephens: 

This letter is in response to your July 22. 201 4 request for the fed eral Ilighway Administration 

(FHWA) to review a roadside safety device, hardware. or system for eligibility for 

reimbursement under the Federal-aid highway program. This Fl IWA letter of eligibility is 

assigned FH\VA control number HSST/CC- 124 and is valid until a subsequent Jetter is issued by 

Fl l \VA that expressly ref ercnccs this device. 

Decision 

The fo llowing devices arc eligible, with details provided in the fo rm which is attached as an 

integral part of this letter: 

•Trinity Slotted Rail Terminal SRT End Terminal Family Ground Strut Modification 

Scope of this Letter 

To be found eligible for Federal-aid funding, modi tied roadside safety devices should meet the 

crash test and evaluation criteria contained in the National Cooperati ve I lighway Research 

Program (NCHRP) Report 350. 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. 

ccrti fication or endorsement of the device for any particular purpose or use. 

This lener is not a determination by the Fl IWA. 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 crash worthiness of the system and does not cover other 

structural features. nor conformity with the Manual on Uniform Traffic Control Devices.

PRODUCT DESCRIPTION 

New Hardware or Modification to IN s· 'fi t 

(' Significant Modification r. Existing Hardware on- igm ican 

The original Slotted Rail Terminal (SRT0 ) as described in Eligibility Letter CC-31 dated December 4, 1995 

specified a yoke design ground strut used between posts 1and 2. A straight flare SRT° with HBA posts was 

subsequently approved In Eligibility Letter CC-72 on December 18, 2000 and used two, (2), 2"x2"x3/8" angle 

ground struts. With the approval ofthe SRT-31 11 for31" high guardrail, a single 3"xrx1/4" angle design ground 

strut was used between posts 1 and 2 and detailed in Eligibility Letter CC-100 dated August 30, 2007. The 

single, 3"x3"x1/4" angle ground strut was also used for the SRT-27° In Eligibility Letter CC-101 dated June 3, 

2008 and the SRT-Ml 0... In Eligibility Letter CC-1008 dated December 5, 2012. 

As detailed In the SRT° time line, the single 3"x3"x1 /4" angle ground strut has been successfully tested In 

various SRT11 systems under both NCHRP Report 350 and the more severe MASH Impact conditions. 

This request Is for the following: 

1. Allow the single 3"x3"x1/4" angle ground strut as a satisfactory replacement for use in the SRT-350° systems. 

This modification has been reviewed and justified through engineering analysis and judgment to be nonslgnlflcant and will have no bearing on the as-tested performance ofthe system. The Testing Laboratory's 

signature concurs that these modifications are considered Non-Significant.

Re: SRTTM Disclosure of Financial Interest, FHWA Review for Eligibility Letter 

Mr. Longstreet, 

On behalf of Trinity Highway Products, LLC (''THP"}, I am responding to your 

email requesting details of any financial interest that the crash test laboratory, that 

performed testing, has in the SRTTM End Terminal Family, manufactured by THP. 

As noted in THP's request for eligibility for reimbursement under the Federal-aid 

highway program for this product, the SRTTM End Terminal system was previously 

deemed eligible by the FHWA pursuant to HNG-14/CC-31, HNG-14/CC-31A HNG14/CC-51, HMHS-CC51A, HSA-1/CC72, HSSD/CC-100, HSST/CC-1008, HSST/CC100C, and HSSD/CC-101. 

The SRTTM end terminal technology is the commercial embodiment of intellectual 

property that is protected by patents that are owned by the Texas A&M University 

System ('TAMUS"). TAMUS licenses the right to manufacture and sell that commercial 

embodiment that is commercially known as the SRTTM End Terminal system, to Trinity. 

THP sponsored certain crash tests of the SRTTM End Terminal system; such tests were 

conducted at the Texas Transportation Institute ("TII") Proving Ground on a campus of 

Texas A&M University. TTI Proving Ground is an International Standards Organization 

("ISO") 17025 accredited laboratory with American Association for Laboratory 

Accreditation (A2LA) Mechanical Testing certificate 2821.01. 

TTI conducted full-scale crash testing of the SRTTM End Terminal system, in 

accordance with the National Cooperative Highway Research Program ("NCHRP") 

testing criteria, first set forth in the NCHRP Report 230 (198X}; then Report 350 (1993); 

and, per the American Association of State Highway and Transportation Officials 

("AASHTO") published testing criteria, as required in the Manual for Accessing Safety 

Hardware (2009) ("MASH"). 

The SRTTM End Terminal system was designed and developed by research 

engineers who are (or were employed} by Texas A&M University at its member, TII.

The associated United States Patent Office patent numbers (5,407,298; 5,503,495) are 

assigned to TAMUS. Additionally, as a modification of the SRTTM End Terminal system, 

the SRTTM End Terminal with Modified Ground Strut patents and financial interests are 

the same as the SRTTM End Terminal. 

THP pays royalties to. TAMUS for sales of the SRTTM End Terminal system 

pursuant to a patent license agreement. TAMUS also received a licensing fee from 

THP at the time of the license agreement execution. 

In accordance with the patent license agreement applicable to this product, the 

specific details of the agreement are "confidential" and cannot be disclosed. If 

necessary, THP is willing to discuss confidential treatment of the content of this license 

agreement with the FHWA, in a manner that does not cause a breach of the license 

agreement. 

Please advise if further information is required by the FHWA. We look forward to 

continuing to work with the FHWA in regard to the SRTTM End Terminal and other 

Roadside Safety Hardware.
