HSST-1/B-304 Mr. Gerrit Dyke, P.E.

Dear Mr. Dyke: 

This letter is in response to your  February 1, 2018 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 B-304 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: 
    QuickChange Moveable Barrier Steel Reactive Tension System (QMBSRTS)***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.
***Eligibility for Reimbursement***
 Based solely on a review of crash test results and certifications submitted by the manufacturer, and the crash test laboratory, FHWA agrees that the device described herein meets the crash test and evaluation criteria of the AASHTO's MASH. Therefore, the device is eligible for reimbursement under the Federal-aid highway program if installed under the range of tested conditions.

Name of system:
      QuickChange Moveable Barrier Steel Reactive Tension System
(QMBSRTS)Type of system:
      Longitudinal Barrier (unanchored)Test Level:
      MASH Test Level 3 (TL3)Testing conducted by:
      Texas A&M Transportation Institute (TamTI)Date of request:
      March 9, 2018Date initially acknowledged:
      March 20, 2018Date of completed package:
      March 9, 2018FHWA concurs with the recommendation of the accredited crash testing laboratory on the attached form. 
   ***Full Description of the Eligible Device***
The device and supporting documentation, including reports of the crash tests or other testing done, videos of any crash testing, and/or drawings of the device, are described in the attached form. 
   ***Notice***
    This eligibility letter is issued for the subject device as  tested. Modifications made to the device are not covered by this letter. Any  modifications to this device should be submitted to the user (i.e., state DOT)  as per their requirements.
   You are expected to supply potential users with sufficient  information on design, installation and maintenance 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 AASHTO's MASH.
Issuance of this letter does not convey property rights of any sort or  any exclusive privilege. This letter is based on the premise that information  and reports submitted by you are accurate and correct. We reserve the right to  modify or revoke this letter if: (1) there are any inaccuracies in the  information submitted in support of your request for this letter, (2) the  qualification testing was flawed, (3) in-service performance or other information reveals safety problems, (4) the system is significantly different from the version that was crash tested, or (5) any other information indicates that the letter was issued in error or otherwise does not reflect full and complete information about the crashworthiness of the system.

   ***Standard Provisions***
   To prevent misunderstanding by others, this  letter of eligibility designated as FHWA control number B-304 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 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.
     This FHWA eligibility letter is not an  expression of any Agency view, position, or determination of validity, scope,  or ownership of any intellectual property rights to a specific device or  design. Further, this letter does not impute any distribution or licensing  rights to the requester. This FHWA eligibility letter determination is made  based solely on the crash-testing information submitted by the requester. The  FHWA reserves the right to review and revoke an earlier eligibility  determination after receipt of subsequent information related to crash testing.
     If the subject device is a patented product it  may be considered to be 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 Brian Fouch for*/* Michael S.
