Dear Mr. Ross

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: Strongwall ADA Pedestrian Barricade / Strongwall LCD
Type of system: Longitudinal Channelizing Device and ADA compliant Pedestrian Barricade
Test Level: MASH Test Level III
Testing conducted by: E-TECH Testing Services
Date of request: June 21, 2013
Request completed: December 14, 2013

Decision:
The following device is eligible, with details provided in the form which is attached as 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 crash test and evaluation 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
To be found eligible for Federal-aid funding, roadside safety devices should meet the crash test and evaluation criteria contained in the American Association of State Highway and Transportation Officials' Manual for Assessing Safety Hardware (MASH).

Description
The device and supporting documentation are described in the attached form, including your request for waiver of MASH Tests 3-70 and 3-72.

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:

 

Sincerely yours,

RE: Draft WZ-328

Dear Sir:

Strongwall ADA Pedestrian Barricade/Strongwall Longitudinal Channelizing Barricade using the recommendations in AASHTO's Manual for Assessing Safety Hardware (MASH).

As recommended in MASH, longitudinal channelizing devices are tested to determine the behavior of the devices during and after impact with both small 1100C (2425 lb/1100kg) and heavy 2270P (5004 lb/2270 kg) vehicles. The risk to occupants from detached elements, fragments, or other debris is assessed, as well as vehicle instability. A key potential risk factor is windshield deformation or penetration Test 90 is designed to evaluate the behavior of the devices during high speed tests, using the 1100C vehicle. This test is recognized as the more critical test by FHWA and, depending on results and device/vehicle geometry, it may be unnecessary to perform Test 91, using the 2270P vehicle. If there is no evidence of vehicle instability or windshield penetration in Test 90, or any belief that these would occur to a pickup truck in a Test 91 situation, a waiver may be requested so that the Test 91 need not be performed. Test 90 was performed with the Strongwall ADA Pedestrian Barricade/Strongwall Longitudinal Channelizing Barricade with the understanding that Test 91 could be waived with appropriate results. This test showed satisfactory results with no apparent vehicle instability or windshield deformation or penetration. Based on the 1100C results and the following analysis of both vehicles' geometry, we request a waiver for Test 91. Here is a summary of the 1100C and 2270P vehicle geometries:

1100C Vehicle Parameters

2270P Vehicle Parameters

The height of the vehicle hood relative to the height of the test device is critical to determining the potential for the device to contact the windshield. The Strongwall device has a total height of 39.4 inches. The 1100C vehicle used for the high speed small vehicle test had a height from the ground to the forward edge of the hood of 28.0 inches (Measurement J). The relationship of the height of the device to the front of the small vehicle is shown here.

Image description can be found in the preceding paragraph

The corresponding ground to edge of hood measurement (Measurement J) for the 2270P vehicle in a Test 91 scenario is 41.3 inches. In this scenario, the hood edge would be 13.3 inches higher than the 1100C vehicle and would be 1.9 inches higher than the device itself. The relationship of the height of the device to the front of the Test 91 pickup truck is shown here:

We conclude that based on the height differential of the pickup truck to the smaller test vehicle and the height relationship to the test article itself, Test 90 was, in fact, the worst case test and it is unlikely that the performance of Test 91 would result in a different outcome.

We request a waiver on Test 91 and issuance of WZ-328.

Thank you.

Dear Sir:

Enclosed is our request for federal-aid reimbursement eligibility for the Plasticade Strongwall ADA Pedestrian Barricade and Longitudinal Channelizing Device. This device was successfully crash tested by E-TECH Testing Services, Inc. on May 14, 2013. A copy of the test report and a DVD with various videos and pictures of the device and the testing process are also enclosed.

The device tested has a panel height that measures 40 inches. We request that our WZ letter of eligibility specifically allow another panel height of 32 inches, consistent with the devices shown in the enclosed literature. As you can see, both panels use the same weighted base.

Please let me know if any additional information is required.

Sincerely,

PLASTICADE
