Federal Highway Administration (FHWA) control number B-373. 

ELIGIBILITY LETTERS

The FHWA issues Federal-aid reimbursement eligibility letters for new roadside safety devices 

that are crash tested in accordance with the industry standard of the American Association of 

State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware 

(MASH). 

FHWA, the Department of Transportation, and the United States (government) do not regulate 

roadside safety devices, crash test facilities, or the manufacturing industry. Issuance of 

eligibility letters is discretionary and provided only as a service to the states. FHWA may, at its 

discretion, decline to issue, revise, or rescind an eligibility letter. Eligibility letters are only 

issued by the FHWA headquarters Office of Safety. 

Eligibility letters are issued only as notice to the states that a device is eligible for reimbursement 

under the Federal-aid highway program. They do not establish approval or certification for any 

other purpose. Issuance of an eligibility letter is not a prerequisite or requirement for state 

transportation agencies seeking to use Federal-aid funds for roadside safety devices. State 

agencies may use a device for which an eligibility letter has not been issued and seek Federal-aid 

reimbursement. 

FEDERAL-AID REIMBURSEMENT

The request for issuance of this letter certified the device was crash tested in accordance with the 

industry standard of AASHTO’s MASH. This eligibility letter is based on that certification and 

the material offered in support of its issuance. The device described below is eligible for 

reimbursement under the Federal-aid highway program.

PRODUCT DESCRIPTION 

New Hardware or Modification to 

Significant Modification Existing Hardware 

The installation consisted of eight reinforced concrete barriers, each 12 ft-6 inches long, for a total installation 

length of 100 ft. Two 7⁄8-inch diameter 30-inch long threaded rods, with a plate washer, washer and heavy hex 

head nut on each end (tightened with impact wrench), connected adjoining barriers to each other in an “X 

pattern.” The barriers were 91⁄2 inches wide at the top, 24 inches wide at the bottom, and 32 inches tall. Each 

barrier had two 3-inch tall × 22 inch long openings at the bottom, and three vertical holes on each side to 

receive anchor pins. The barriers were secured to the working slab with one 1-inch diameter × 25-inch long 

anchor pin located on the traffic side, at each end of each barrier units. These pins anchored the barrier units 

completely through a 10-inch thick unreinforced concrete slab and into the subgrade below.

Results 

3-10 (1100C) 

Test 3-10 (WSP-3) involves an 1100C vehicle 

impacting the test article at a target impact 

speed of 62 mi/h ±2.5 mi/h and a target 

impact angle of 25° ±1.5°. The target CIP 

was determined using the information 

provided in MASH Section 2.2.1, Section 

2.3.2, and Table 2-7 and was for the right 

corner of the front bumper to impact at 3.6 

ft upstream of the centerline of the joint 

between barriers 4 and 5. 

The results of the test conducted on 

September 14, 2020, are found in TTI Test 

Report number 690900-WSP -3-4. The test 

vehicle was traveling at an impact speed of 

64.5 mi/h as it made contact with the barrier 

3.2 ft upstream of the barrier joint between 

barriers 4 and 5 at an impact angle of 25.0°. 

After loss of contact with the barrier, the 

vehicle came to rest 220 ft downstream of 

the impact point and 43 ft towards the field 

side. 

The barrier contained and redirected the 

1100C vehicle. The vehicle did not 

penetrate, underride, or override the 

installation. The 1100C vehicle exited within 

the exit box criteria. 

Working width was 28.0 inches at a height 

of 3.0 inches. Dynamic deflection of the 

barrier during the test was 8.0 inches, and 

permanent deflection was 4.0 inches. 

Although small pieces of concrete spalled 

off of the barrier, no detached elements, 

fragments, or other debris were present to 

penetrate or show potential for penetrating 

the occupant compartment, or present 

hazard to others in the area. 

Maximum exterior crush to the vehicle was 

9.0 inches in the side plane at the right front 

corner at bumper height. Maximum 

occupant compartment deformation was 

1.5 inches in the right kick panel area. 

The 1100C vehicle remained upright during 

and after the collision event. Maximum roll 

and pitch angles were 9° and 17°, 

respectively. Longitudinal OIV was 20.0 ft/s, 

and lateral OIV was 26.9 ft/s. Longitudinal 

occupant ridedown acceleration was 3.4 g, 

and lateral occupant ridedown acceleration 

7.9 g. The occupant risk factors were 

within the MASH preferred limits. 

The Pinned Temporary Concrete Barrier 

performed acceptably for MASH test 3-10.

impacting the test article at a target impact 

speed of 62 mi/h ±2.5 mi/h and a target 

impact angle of 25° ±1.5°. The target CIP 

was determined using the information 

provided in MASH Section 2.2.1, Section 

2.3.2, and Table 2-7 and was for the right 

corner of the front bumper to impact at 4.3 

ft upstream of the centerline of the joint 

between barriers 4 and 5. 

The results of the test conducted on 

September 16, 2020 are found in TTI Test 

Report number 690900 WSP -3-4. The test 

vehicle was traveling at an impact speed of 

63.9 mi/h as it made contact with the barrier 

3.9 ft upstream of the barrier joint between 

barriers 4 and 5 at an angle of 25.2°. After 

loss of contact with the barrier, the vehicle 

came to rest 220 ft downstream of the 

impact point and 9 ft towards the field side. 

The barrier contained and redirected the 

2270P vehicle. The vehicle did not 

penetrate, underride, or override the 

installation. The 2270P vehicle exited within 

the exit box criteria. 

Working width was 34.4 inches at a height 

of 3.0 inches. Dynamic deflection of the 

barrier during the test was 17.9 inches, and 

permanent deflection was 10.0 inches. 

Although small pieces of concrete spalled 

off of the barrier, no detached elements, 

fragments, or other debris were present to 

penetrate or show potential for penetrating 

the occupant compartment, or present 

hazard to others in the area. 

Maximum exterior crush to the vehicle was 

12.0 inches in the front and side planes at 

the right front corner at bumper height. 

Maximum occupant compartment 

deformation was 1.0 inches in the right 

front firewall area. 

The 2270P vehicle remained upright during 

and after the collision event. Maximum roll 

and pitch angles were 18° and 20°, 

respectively. Longitudinal OIV was 14.4 ft/s, 

and lateral OIV was 21.0 ft/s. Longitudinal 

occupant ridedown acceleration was 4.1 g, 

and lateral occupant ridedown acceleration 

11.4 g. The occupant risk factors were 

within the MASH preferred limits.
