Dear Mr. Ganster:

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: Delta Bloc DB 80 F-Shape 12 ft 6 in long units
Type of system: Portable concrete barrier
Test Level: MASH Test Level 3
Testing conducted by: Midwest Roadside Safety Facility
Task Force 13 Designator: SWC18
Date of initial request: October 5, 2011
Date initially acknowledged: December 20, 2011
Date of completed package: December 19, 2012

Decision:
The following device is eligible, with details provided in the enclosed form which is considered an integral part of this letter:

Based on a review of crash test results submitted by the manufacturer certifying the device described herein meets the crashworthiness criteria of the American Association of State Highway and Transportation Officials’ Manual for Assessing Safety Hardware (MASH), 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 the MASH.   

Description and Crash Tests
The enclosed copy of your form, as well as the letter from Thomas Wolfe sent on October 5, 2011, details the construction of the barrier as well as tests 3-10 and 3-11, both of which were conducted in compliance with the MASH and resulted in successful performance. Vehicle trajectory, barrier structural adequacy, and occupant risk factors conformed to the evaluation criteria contained in the MASH.

Findings
Therefore, the system described and detailed in the attached letter, drawings, and test data summary 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:

 

Sincerely yours,
