Dear Mr. Goode:
In your letter of August 18, 2008, received September 2, 2008, you requested the Federal Highway Administration (FHWA) acceptance of the SZ-460-2S and the SZ-484-2S temporary sign stands with the following sign substrate materials: 0.08 inch thick aluminum, 3 mm and 4 mm aluminum composite, fiberglass supported roll-up signs, 6.35 mm solid ABS plastic, 10 mm and 16 mm corrugated plastic, and sign sizes up to the tested limit of 48 inches by 48 inches as crashworthy traffic control devices for use in work zones on the National Highway System (NHS). You requested acceptance of a 48 inch by 48 inch diamond installation and a 48 inch by 60 inch rectangular installation. Accompanying your letter was the FHWA Office of Safety Design form that included a drawing and a detailed description of the barricade, a test report, and videos of the crash test. The drawing is enclosed with the acceptance form for the Type I barricade. You requested that we find this device acceptable for use on the NHS under the provisions of National Cooperative Highway Research Program Report 350 "Recommended Procedures for the Safety Performance Evaluation of Highway Features”.
This letter acknowledges FHWA's acceptance of your requests. The original completed forms have been modified by the addition of the FHWA acceptance letter number and the date of our review. The form will be posted on our Web site in the near future.
Sincerely yours,
David A. Nicol, P.E. |
