Dear Mr. Ross:

This is in response to your September 1, 2010, letter requesting the Federal Highway Administration's (FHWA) acceptance of your company's EconocadeTM Type I and Type II Barricades with lightweight warning lights as crashworthy traffic control devices for use in work zones and elsewhere on the National Highway System (NHS). Accompanying your letter was the FHWA Office of Safety Design form indicating successful performance when tested under the AASHTO Manual for Assessing Safety Hardware (MASH) Test 3-71 (Modified.)

Device Fibercade Type II Barricade Econocade Type I and
Test # 400001-ALB3 N/A
Height, mm (in)# 1075 (42 )# 1016 (40
Height to top of light 1313 (52) 1240 (48)
Mass (without light*) 6.9 kg (15.2 lbs.) 6.0 kg (13.2 lbs.)
Mass 10.5 kg (23.1 lbs.)
Mass, plus ballast 29.7 kg (65.5 lbs.)
Vehicle Speed, km/h 97.5, 92.7 N/A
Velocity Change,m/s 1.33, 2.06 N/A
Windshield Damage None N/A

You requested that we find the Econocade™ Barricades with lightweight warning lights acceptable for use on the NHS under the provisions of the National Cooperative Highway Research Report 350 and MASH based on its equivalence to your previously crash-tested Plasticade™ barricade. The Plasticade was found acceptable in FHWA Acceptance Letter WZ-14 dated May 28, 1999. As no additional crash testing was conducted under MASH criteria, our acceptance will be limited to performance under NCHRP Report 350.

The Econocade™ Barricades described above and detailed in the enclosed drawing is equivalent to the tested barricade as it is now molded as one piece and expected to perform in the same manner as the tested barricade. Therefore, they are acceptable for use on the NHS under the test conditions noted above, when such use is acceptable to a highway agency.

Please note the following standard provisions that apply to FHWA letters of acceptance:

 

Sincerely yours,

Signature Michael S. Griffith
