Austria 

Dear Mr. Redlberger: 

This letter is in response to your November 27, 2017 request for the Federal Highway 

Administration (FHW A) to review a roadside safety device, hardware, or system for eligibility 

for reimbursement under the Federal-aid highway program. This FHW A letter of eligibility is 

assigned FHW A control number B-301 and is valid until a subsequent letter is issued by FHW A 

that expressly references this device. 

Decision 

The following device is eligible within the length-of-need, with details provided in the form 

which is attached as an integral part of this letter: 

• RB80S 12 

Scope of this Letter 

To be found eligible for Federal-aid funding, new roadside safety devices should meet the crash 

test and evaluation criteria contained in the American Association of State Highway and 

Transportation Officials' (AASHTO) Manual for Assessing Safety Hardware (MASH). 

However, the FHW A, the Department of Transportation, and the United States Government do 

not regulate the manufacture of roadside safety devices. Eligibility for reimbursement under the 

Federal-aid highway program does not establish approval, certification or endorsement of the 

device for any particular purpose or use. 

This letter is not a determination by the FHW A, the Department of Transportation, or the United 

States Government that a vehicle crash involving the device will result in any particular 

outcome, nor is it a guarantee of the in-service performance of this device. Proper 

manufacturing, installation, and maintenance are required in order for this device to function as 

tested. 

This finding of eligibility is limited to the crashworthiness of the system and does not cover other 

structural features, nor conformity with the Manual on Uniform Traffic Control Devices. 
2 

Eligibility for Reimbursement 

Based solely on a review of crash test results and certifications submitted by the manufacturer, 

and the crash test laboratory, FHW A agrees that the device described herein meets the crash test 

and evaluation criteria of the AASHTO's MASH. Therefore, the device is eligible for 

reimbursement under the Federal-aid highway program if installed under the range of tested 

conditions. 

Name of system: RB80S _ 8 


Type of system: Longitudinal Barrier 


Test Level: MASH Test Level 3 (TL3) 


Testing conducted by: MIRA, Ltd. 


Date of request: December 6, 201 7 


Date initially acknowledged: December 6, 2017 


FHW A concurs with the recommendation of the accredited crash testing laboratory on the 

attached form. 

Full Description of the Eligible Device 

The device and supporting documentation, including reports of the crash tests or other testing 

done, videos of any crash testing, and/or drawings of the device, are described in the attached 

form. 

Notice 

This eligibility letter is issued for the subject device as tested. Modifications made to the device 

are not covered by this letter. Any modifications to this device should be submitted to the user 

(i.e., state DOT) as per their requirements. 

You are expected to supply potential users with sufficient information on design, installation and 

maintenance 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 test 

and evaluation criteria of AASHTO's MASH. 

Issuance of this letter does not convey property rights of any sort or any exclusive privilege. This 

letter is based on the premise that information and reports submitted by you are accurate and 

correct. We reserve the right to modify or revoke this letter if: (1) there are any inaccuracies in 

the information submitted in support of your request for this letter, (2) the qualification testing 

was flawed, (3) in-service performance or other information reveals safety problems, (4) the 

system is significantly different from the version that was crash tested, or (5) any other 

information indicates that the letter was issued in error or otherwise does not reflect full and 
3 

complete information about the crashworthiness of the system. 

Standard Provisions 

• 	 To prevent misunderstanding by others, this letter of eligibility designated as FHW A 

control number B-301 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 upon request. 

• 	 This letter shall not be construed as authorization or consent by the FHW A to use, 

manufacture, or sell any patented system for which the applicant is not the patent holder. 

• 	 Ifthe subject device is a patented product it may be considered to be proprietary. If 

proprietary systems are specified by a highway agency for use on Federal-aid projects: 

(a) they must be supplied through competitive bidding with equally suitable unpatented 

items; (b) the highway agency must certify that they are essential for synchronization 

with the existing highway facilities or that no equally suitable alternative exists; or (c) 

they must be used for research or for a distinctive type of construction on relatively short 

sections of road for experimental purposes. Our regulations concerning proprietary 

products are contained in Title 23 , Code of Federal Regulations, Section 635.411.

PRODUCT DESCRIPTION 


le' New Hardware or 

•. Significant Modification 

('.Modification to 

Existing Hardware 

The vehicle restraint system with the system name REBLOC RB80S_12 consists of factory produced precast 

elements, each element is 12.00m long, 0.30m wide and 0.80m high. The precast concrete elements have a 

cross section similar to an I-beam profile. 

The safety barriers are free standing, i.e. there is no anchorage to the ground, and only the two terminal 

elements have to be anchored to the asphalt surface by using anchor bolts. 

The restraining function is achieved by connecting the individual elements to form a continuous chain. The 

connection between the elements is by the integrated tension bars, whose couplings, situated on the face side 

of each element, interlock. Steel shoes which are part of the element, have mating projections and 

indentations that formed a double tongue/groove system. The concrete barriers stand on four support feet 

with elastomer pads on the underside. Situated at the top side of each element there are two galvanized lifting 

anchors. 

CRASH TESTING 

By signature below, the Engineer affiliated with the testing laboratory, agrees in support of this submission that 

all of the critical and relevant crash tests for this device listed above were conducted to meet the MASH test 

criteria. The Engineer has determined that no other crash tests are necessary to determine the device meets 

the MASH criteria.

T0231, 31st May 2017, 1214221-001-01: 


The critical impact point was designated as 


being the first point of contact of the 


vehicle with the barrier which was at the 


mid-point of barrier unit #3 of the ?units 


installed. Since the barrier was a continuous 


solid unit there was minimal risk of under-


riding, over-riding or pocketing/wheel snag 


and so CIP was chosen to be with the 


vehicle impacting the most resistive part of 


3-10 (11 OOC) the barrier and thus generating the highest 

occupant severity indices. The vehicle made 

contact with the barrier causing it to move 

away from the orig inal traffic face line. The 

vehicle was redirected and ran along in 

contad with the barrier traffic face for the 

remaining length of system. The remote 

braking system brought the vehicle to halt 

73m downstream of impact point and 4m in 

front of the traffic face. 

PASS 

3-11 (2270P) 

T0232, 1st Jun 2017, 1214221-002-01 : 


The critical impact point was designated as 


being the first point of contact of the 


vehicle with the barrier was at point 1 .3m 


upstream of the joint between units #3 and 


#4. Since the barrier was a continuous solid 


unit there was minimal risk of under-riding, 


over-riding or pocketing/wheel snag and so 


CIP was chosen to be with the vehicle 


impacting the most flexible part of the 


barrier (joint) and thus generate the 


greatest barrier deflection. The vehicle 

made contact with the barrier causing it to 

move away from the original traffic face line 

and roll slightly backwards, lifting the front 

foot of the units. The vehicle was redirected 

away from the traffic face, the rear end 

rising up in the air, and when it left the 

barrier, the system returned to almost 

vertical. The remote braking system 

brought the vehicle to halt l 99ft. (61 m) 

downstream of impact point and 8.Sft. 

(2.6m) in front of the traffic face.
