Dear Mr. Dyke:
This letter is in response to your request for the Federal Highway Administration (FHWA) to review a roadside safety system for eligibility for reimbursement under the Federal-aid highway program.
Name of system:
      X-Lite Tangent and X-Lite Flared Soil Plate ModificationType of system:
      W-Beam Guardrail TerminalTest Level:
      NCHRP 350 Test Level 3 (TL-3)Original Testing conducted by:
      Safe Technologies, Inc.Finite Element Analysis conducted by:
      Politecnico di Milano, ItalyTask Force 13 Designator:
      SEW23B Tangent; SEW24B FlaredDate of request:
      July 16, 2013Date initially acknowledged:
      December 17, 2013**Decision:**
The following device is eligible, with details provided in the form which is attached as an integral part of this letter:
X-Lite Tangent and X-Lite Flared Soil Plate ModificationBased on a review of FEA Analysis and Verification and Validation as per FHWA Memorandum â€œRoadside Safety Hardware-Federal-aid Reimbursement Eligibility Processâ€�, Dated May 21, 2012 of the modified device compared to original crash test results submitted by the manufacturer certifying the device described herein meets the crashworthiness criteria of the National Cooperative Highway Research Program (NCHRP) Report 350, the device is eligible for reimbursement under the Federal-aid highway program.  Eligibility for reimbursement under the Federal-aid highway program does not establish approval or endorsement by the FHWA for any particular purpose or use.  The FHWA, the Department of Transportation, and the United States Government do not endorse products or services and the issuance of a reimbursement eligibility letter is not an endorsement of any product or service.
**Requirements:**Roadside safety devices should meet the guidelines contained in NCHRP Report 350 (Report 350) if tested prior to January 1, 2011, or the American Association of State Highway and Transportation Officialsâ€TM Manual for Assessing Safety Hardware (MASH) if tested after that date.  The FHWA Memorandum "Identifying Acceptable Highway Safety Features", dated July 25, 1997, provides further guidance on crash testing requirements of longitudinal barriers.
**Description**
The modified 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.
  You are  expected to supply potential users with sufficient information on design and  installation requirements to ensure proper performance.
  You are  expected to certify to potential users that the hardware furnished has the same  chemistry, mechanical properties, and geometry as that submitted for review,  and that it will meet the test and evaluation criteria of the MASH.
  To  prevent misunderstanding by others, this letter of eligibility is designated as  number CC-120B and shall not be reproduced except in full. This letter and the test documentation upon  which it is based are public information.    All such letters and documentation may be reviewed at our office upon  request.
  This  letter shall not be construed as authorization or consent by the FHWA to use,  manufacture, or sell any patented system for which the applicant is not the  patent holder.   The FHWA does not become  involved in issues concerning patent law. Patent issues, if any, are to be  resolved by the applicant.
  The X-Lite  Tangent (TX) Modified, X-Lite Flared (FX) Modified Terminals are patented products and considered proprietary.   If proprietary systems are specified by a  highway agency for use on Federal-aid projects: (a) they must be supplied  through competitive bidding with equally suitable unpatented items; (b) the  highway agency must certify that they are essential for synchronization with  the existing highway facilities or that no equally suitable alternative exists;  or (c) they must be used for research or for a distinctive type of construction  on relatively short sections of road for experimental purposes.   Our regulations concerning proprietary  products are contained in Title 23, Code of Federal Regulations, Section  635.411.Sincerely yours,
Signature of Michael S. Griffith
