PRODUCT DESCRIPTION 

Modification to €New Hardware \;

·,, Existing Hardware 

The Low-Deflection Portable Concrete Barrier Version 1system (SWC20a) Is comprised of Portable F-shape 

Concrete Barrier Element (SWC09) joined with the Portable Concrete Barrier Connector Pins with or without the 

retainer bolt (FMW02 or FMW03) and stiffened by attachment ofasteel cap across each joint ofthe barrier 

system and the addition of tubular beams on both faces of the barrier. The system is not anchored to the 

roadway surface and Is designed for use with PCB segments (SWC09) placed In a straight line or large-radius 

curves where the design tolerances can accommodate the small angels between adjacent barrier segments. A 

42-in. long, 10-gauge, ASTM A1011 Grade SO bent steel cap was centered across each joint and through-bolted 

to the barriers with either four 12 3/4-ln. long, ASTM A449 bolts with nuts (FBX24b) and washers (FWC24a) on 

both sides of the barrier or four 14-ln. long, ASTM A449 threaded straight anchor studs with nuts (FRS24b) and 

washers (FWC24a) on both sides ofthe barrier. A 153 3/6-ln. long, 5-ln. x 5-ln. x 3/16-ln. ASTM A500 Grade B 

steel tube was welded to the steel cap on both sides of the barrier. The steel tubes were spliced at the center of 

each Portable F-shape Concrete Barrier Element (SWC09). Each splice contained a 22-in. long, 4 1/2-ln. x 4 1 /2-in. 

x 1 /2-in. U-shape bent ASTM A572 Grade SO steel splice Insert which was placed Inside the end of each of the 

adjoining tubes. The tube splices were bolted together on both the front and back sides with four 6 1 /2-ln. long, 

3/4-in. diameter Grade 5 bolts with nuts (FBX20a) and washers (FWC20a) under the head of the bolt and the 

nut. The bolts and threaded anchor studs should not have more than 1/2 in. of length exposed past the end of 

the nut.

Subject: Small Car Test Waiver Information 

Dear Will: 

This letter is intended to address the request by FHWA for additional information 

pertaining to vehicle stability of the small car in regards to the Retrofit. LowDeflection Portable Concrete Barrier Version 1 for which we are requesting a letter 

of eligibility on behalf of the state departments of transportation participating in the 

Midwest States Regional Pooled Fund Program, specifically Wisconsin Department of 

Transportation. 

In test no. 7043-2 found in Volume II - Appendices of NCHRP Project 22-6 (final 

report NCHRP 318), a rigid, New Jersey shape concrete barrier was successfully 

impacted by a small car weighing l,722 lb at 59.9 mph and 21.9 degrees similar to the 

standards set forth in NCHRP 350. In test no. 7043-12 found in Volume II ­

Appendices of NCHRP Project 22-6 (final report NCHRP 318), a rigid, New Jersey 

shape concrete barrier was successfully impacted by a small car weighing 1,695 lb at 

61.6 mph and 20. l degrees similar to the standards set forth in NCHRP 350. In test no. 

7069-3 found in FHWA report nos. FHWA-RD-93-058 and FHWA-RD-93-064, a rigid, 

F-shape bridge rail was successfully impacted by a small car weighing 1,800 lb at 60. l 

mph and 21.4 degrees according to the American Association of State Highway and 

Transportation Officials (AASHTO) Guide Specifications for Bridge Railings. 

During all three tests, the small car climbed the face of the barrier and became airborne. 

Although the small cars were airborne for a brief period, the vehicle remained upright 

and was smoothly redirected. The geometry of the F-shape exhibited improved vehicle 

stability characteristics when compared to the New Jersey shape even though both 

barrier shapes allow the small car to climb the face of the barrier. 

Further, in test no. 2214NJ-l found in MwRSF report no. TRP-03-177-06, a rigid, New 

Jersey safety shape barrier was successfully impacted by a passenger car weighing 

2,579 lb at 60.8 mph and 26. l degrees according to the TL-3 standards set forth in 

MASH. The l l OOC vehicle once again climbed the face of the barrier and became 

airborne, but remained upright and was smoothly redirected. Therefore, based on the 

above noted tests, the l l OOC passenger car test was believed to be unnecessary for this 

system.

Subject: Small Car Test 

Dear Will: 

This letter is intended to address the question pertaining to concerns for occupant 

compartment intrusion with the 11 OOC vehicle raised by FHWA in regards to the 

Retrofit. Low-Deflection Portable Concrete Barrier Version 1 and Version 2 for 

which we are requesting a letter of eligibility on behalf of the state departments of 

transportation participating in the Midwest States Regional Pooled Fund Program, 

specifically Wisconsin Department of Transportation. 

The top rail height for the low-deflection PCB system is 29". This height was based on 

the 27" and 28" heights of the previously tested box beam roadside and median barrier 

systems, respectively. The height was adjusted to 29" due on connection and 

interference issues with the PCB reinforcement. This height was not believed to be an 

issue as the height of the small car (11 OOC) vehicle window is generally over 31 ". Thus, 

the height of the box beam rail is lower than the A-pillar, windshield, and side-window 

structures, and the potential for the box beam to intrude or cause excessive damage in 

these areas is minimal. 

Additionally, the box beam is mounted on an F-shape PCB. Typically, small cars that 

interact with the toes of F-shape barriers tend to climb the barrier and roll away from 

the face of the barrier. This motion would further reduce the potential for damage to the 

A-pillar or other areas above the door frame by the box beam. The box beam railing 

used in the system is a continuous element that is spliced longitudinally similar to other 

box beam and tubular bridge rail designs. The box beam is anchored to the PCB at the 

cap over the PCB joint and at the mid-section of the barrier. This prevents the tubes 

from disengaging from the PCB and becoming an intrusion hazard. The increased 

impact loading of the 2270P impacts would have indicated any potential for the tubes to 

disengage or separate. 

Previous testing with small cars on an identically similar system does not exist, but 

similar testing appears to indicate that it is not a safety concern. Previous testing of 

box-beam systems or tubular bridge rails, as summarized below, has not indicated that 

occupant compartment deformation of the small cars due to the tubes is an issue. 

I. 	In test no. 4 73160-8, a box-beam transition to two tube bridge rail was evaluated 

according to NCHRP 350 Test Level 3 (TL-3) with the 820C vehicle. The 

transition had a top rail height of 29". This test passed NCHRP 350 with a 

130 Whittier Reseaich Center I P.O. Box 830853 I Unccln, NE 68583-0853 I mwrsf.unl.edu 
similar rail height and a much stiffer tubular rail configuration than the lowdeflection PCB system which deflects approximately 40". While the angle of the 

NCHRP 350 test was 20 degrees rather than the 25 degrees required by MASH, 

this test would suggest that there is minimal concern for occupant compartment 

deformation for MASH test designation no. 3-10. 

2. 	 In test no. 7202-5, a box beam median barrier terminal was evaluated according 

to NCHRP 350 TL-3 with the 820C vehicle. The box beam median terminal had a 

rail height of 28". The small car was safely redirected and no occupant 

compartment concerns arose. Again, the tests were not identical to the lowdeflection PCB system in terms of impact conditions and the rail height is 

slightly lower by l ". However, it further indicates that occupant compartment 

intrusion would be a concern. 

Therefore, based on a comparison of similar previous testing and engineering analysis 

of the box-beam rail height mounted on the low-deflection PCB system· relative to the 

vehicle structure, we do not believe that occupant compartment deformation or 

intrusion concerns warranted conducting MASH test designation no. 3-10, the 11 OOC 

small car vehicle. 

Lastly, this letter is intended to further clarify the Not Applicable statement in the 

Narrative Description for Required Test Number 3-20 and 3-21 in the Request for 

Federal Aid Reimbursement Eligibility of Highway Safety Hardware form submitted. 

Not Applicable means that test numbers 3-20 and 3-21 are not applicable for this type 

of system.

INTENDED USE 

Retrofit, Low-DcOcction. Portable Concrete Barrier is a non-proprietary system and is to be used in situations where limited system 

dcOection is required. The Retrofit, Low-DeOcction, Ponablc Concrete Barrier should be used in locations where a maximum dynamic 

deflection of 43.0" [ 1,092) or less is acceptable and where a working width of 55. 1" ( 1,400] is provided. The Retrofit. LowDeflection. Ponablc Concrete Barrier with L-Brackcts should be used in locations where a maximum dynamic deOcction of 40.7" 

[1.034] or less is acceptable and where a working width of 51.9" [ 1.318] is provided. The system should be placed with n minimum 

distance of 24" [610) between the back face of the concrete barrier and the edge of the bridge deck or drop off. Retrofit, LowDeflection, Ponable Concrete Barrier may be used on n concrete or asphalt surface. The Retrofit, Low-Deflection, Portable Concrete 

Barrier system is intended fo r use with the Ponablc F-shapc Concrete Barrier Element (SWC09) and lhc Portable Concrete Barrier 

Connector Pins with or without the ret::1iner bolt (FM\V02 or FM\V03). The Portable F-shape Concrete Barrier Elements (SWC09) are 

to be placed in a straight line or a large radius curve where the existing design tolerances can accommodate the small angles between 

adjacent Ponable F-shape Concrete Barrier Element::. (SWC09). TI1e Retrofit, Low-Deflection. Ponablc Concrete Barrier has been 

crash tested under Test Level 3 (TL-3) conditions of the ~lanual for Assessing Safety Hardware (MASH) and deemed acceptable 

according to the MASH safety perfonm1nce cri teria.
