SPECIFICATIONS

Modified Thrie-Beam guardrail blockouts shall be manufactured using AASHTO M 270 / M 270M
(ASTM A 709 / A 709M) Grade 36[250] steel, unless corrosion-resistant steel is required, in which
case the blockout shall be manufactured from AASHTO M 270/ M 270M (ASTM A 709 / AO9M)
Grade 50W [345W] steel. The dimensions of the structural shapes, M14x18 [M360x25.6] and
W6x9 [W150x13.5], are defined in AASHTO M 160/M 160M (ASTM A 6/ A 6M).

After the section is cut and all holes are drilled or punched, the component should be zinc-coated
according to AASHTO M 111 (ASTM A 123) unless corrosion-resistant steel is used, in which
case it should not be zinc-coated, painted or otherwise treated.

Dimensional tolerances not shown or implied are intended to be those consistent with the proper
functioning of the part, including its' appearance and accepted manufacturing practices.

INTENDED USE

This blockout is used in the SGRO9b and SGM09b strong-post modified Thrie-Beam guardrail and
median barrier. Each blockout is attached to PWE04 posts with at least two 1.5-inch [40 MM] long
zinc-coated FBX 16a bolts and nuts. The Thrie-Beam is attached to the blockout using an FBB02

guardrail bolt and nut.

PRODUCT DESCRIPTION

[The Task Force 13 designator for this blockout is PWB03. As currently documented, there are no tolerances for
ithe triangular cutout or a defined amount of web material that may remain after the removal process. Typical
manufacturing methods leave some amount of web material depending on the process and equipment used.

This component modification defines the maximum amount of web that may be retained and maintain
successful crash testing results. Trinity Highway Products, LLC. contracted with Texas A&M Transportation
Institute (TTI) to crash test the modified steel thrie beam blockout with a maximum web cutout. Crash testing
found that the bleckout successfully meet NCHRP 350 Test Level 4 impact criteria.

The tested modified thrie beam blockout was manufactured from standard W14X22 Wide Flange Steel W-Beam
that conforms to ASTM A36 specifications. A triangular section seven inches (7") high by six inches (6") deep
with a one quarter inch radius (1/4°R) was removed from the web. The triangular cutout begins one and one
quarter inches (1-1/4") from the outer edge of the beam flange.

Crash testing confirmed that the manufacturing tolerances of the triangular cutouts that begin flush with the
jouter flange or any range up to and including this tested distance (1-1/4" from outer flange edge) will behave
similarly and provide consistent, successful NCHRP 350 Test Level 4 results. This component madification
(defined tolerances associated with the location of the triangular cutouts) for an improved modified steel thrie
beam blockout is considered Non-Significant and will have an inconsequential effect.

area. No occupant compartment deformation or intrusion
loccurred. The modified thrie beam guardrail system performed
lacceptably according to required specifications for NCHRP Report

Requirements

To be found eligible for Federal-aid funding, roadside safety devices should meet the crash test
and evaluation criteria contained in the National Cooperative Highway Research Program
(NCHRP) Report 350 or 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.

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:

This letter provides a AASHTO/ARTBA/AGC Task Force 13 designator that should
be used for the purpose of the creation of a new and/or the update of existing Task
Force 13 drawing for posting on the on-line ‘Guide to Standardized Highway Barrier
Hardware’ currently referenced in AASHTO Roadside Design Guide.

This finding of eligibility does not cover other structural features of the systems, nor
conformity with the Manual on Uniform Traffic Control Devices.

Any changes that may influence system conformance with NCHRP Report 350
criteria will require a new reimbursement eligibility letter.

Should the FHWA discover that the qualification testing was flawed, that in-service
performance reveals safety problems, or that the system is significantly different from
the version that was crash tested, we reserve the right to modify or revoke this letter.
You are expected to supply potential users with sufficient information on design and
installation 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 crash test and evaluation criteria of the NCHRP Report 350.
To prevent misunderstanding by others, this letter of eligibility is designated as
number B-248 and 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 at our office 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. The FHWA does not become involved in issues concerning patent law.
Patent issues, if any, are to be resolved by the applicant.
