Dear Mr. James: 

This lener is in response to your request for Federal Highway Administration (FHWA) 

acceptance of a roadside safety system for use on the National Highway System (NHS). 

Name of system: X-LITE Terminal 

Type of system: Tangcnl & Flared Re-directive Gating W-Beam Terminal 

Test Level: NCHRP Report 350 TL-3 

Testing conducted by: Safe Technologies Inc. 

Date of request: December 20, 20 I0 

Request acknowledged: December 27, 20 10 

Task Force 13 Designator: SEW23 Tangent 

SEW24 Flared 

You requested that we find this system acceptable for use on the NHS under the provisions of the 


National Cooperative Highway Research Program (NCHRP) Report 350 "Recommended 


Procedures for the Safety Performance Evaluation of Highway Features." 


Requirements 


Roadside safety devices tested prior co January I, 20 I I should meet the guidelines contained in 


NCHRP Report 350; those tested after that da te must foil ow the guidelines contained in the 


American Association of State Highway and Transportation Officials' (AASHTO) Manual for 


Assessing Safety Hardware (MASH). The FHWA Memorandum " Identifying Acceptable 


Highway Safety Features" of July 25, 1997 provides further guidance on crash testing 


requirements for longitudinal barriers. 


Decision 


The following barrier design was found acceptable, with details provided below:

Description 

The X-LITE Terminal evolved from the original X-Tension Terminal (FHWA letter CC-91) and 

incorporates many of the key components and design features ofthe X-Tension. Like the earlier 

design, the X-LITE Terminal absorbs the kinetic energy of the impacting vehicle when struck head 

on by telescoping the W beam panels, gathering and retaining the rails into the slider mechanism. 

The friction applied by the slider mechanism increases with each additional rail that it gathers and 

retains, thereby gradually increasing the energy absorbing capability ofthe X-LITE Terminal. 

When hit at an angle at or beyond the third post, the X-LITE Terminal is restrained laterally by the 

W-Beam panels and its end anchor. This anchor consists of posts #1 and #2 connected by tension 

struts and a soil plate below grade on post #2. 

The X-LITE Terminal consists of 3 standard W-beam panels installed on I-beam posts. using either 


composite or routed wood offset blocks. It can be installed parallel to the roadway or flared with a 


1220-millimeter (48-inch) offset over 11.4 meters (37.5 feet), there are 6 modified (crimped) posts 


used in the flared design and 3 in the tangent design, including post #2 in both designs. The flared 


design includes an offset block at post #2, whereas the tangent design does not. For both layouts, 


only the offset block is bolted to post #5. Based on the test results reported below, the X-LITE can 


be installed with the top ofthe rail at either 702 millimeters (27 5/8 inches) or 787 millimeters (31 


inches) above grade. The slider mechanism is at the joint between rails I and 2, with shear bolts at 


the joint between rail 2 and 3. An additional set of shear bolts between rails 3 and 4 are used in the 


tangent system only. 


Enclosures I and 2 show the design and assembly of the flared and tangent X-LITE Terminal 


systems respectively. 


Crash Testing 


The crash test matrix was developed in consultation with the FHWA's Office of Safety Design 


and the following tests were conducted to validate the crashworthiness of the X-LITE Terminal: 


NCHRP Report 350 test designations 3-31 and 3-35 were conducted on the flared system at 27 


5/8 inches high and test 3-30 was run using a rail height of 31 inches; tests 3-31 and 3-30 were 


also run on the tangent system. To provide additional support of the X-LITE at 31 inches high, 


test 3-34 was run on the X-Tension Terminal. Each of these tests is briefly described below. 


Flared design: 


Test 3-30 was conducted with the rail height set at 787 millimeters (31 inches) to verify that the 


820C vehicle would not underride the impact head. Enclosure 3 is the summary sheet for this 


test. 


Test 3-31 was conducted with the rail height set at 702 millimeters (27 5/8 inches) to verify 


impact performance with the 2000P test vehicle. The pickup truck proceeded through the 


terminal and came to rest behind the test installation. 27 meters (approximately 90 feet) 


downstream from the impact point. While this trajectory is common to all Oared. gating W­


beam terminals, it serves to emphasize the importance of a clear and traversable runout area 


behind and beyond such terminals. Enclosure 4 is the summary sheet for this test. 


Test 3-34 with the 820C vehicle impacting the side ofthe system at the critical impact point 


(CIP) at a 15-degree angle was conducted using the flared X-Tension design at the 787­

millimeter (31-inch) height. Since the X-Tension has only two weakened posts at the front, 

followed by standard steel line posts, this test was considered to be a more severe test of wheel 

snag than the X-LITE with its six crimped posts. Enclosure 5 is the summary sheet for this test. 

Test 3-35 was conducted with the 2000P vehicle impacting the side of the terminal at post #3 at a 

nominal angle of 20 degrees. Because of the flared terminal layout, the actual impact angle was 

approximately 26 degrees. For this test, the lower rail height of 702 millimeters (27 5/8 inches) 

was used. The pickup truck was contained and redirected, thus confirming the barrier length of 

need (LON) begins at post #3. Enclosure 6 is a summary of the test conditions and results. 

In your request, you noted that tests 3-32 and 3-34 were not run because these tests have always 

been shown to be less severe than the end-on tests for gating terminals. Test 3-39, a reversedirection, 20 degree test with the pickup truck was not run on the flared X-LITE design based on 

the successful performance of the tangent X-Tension test which you conducted during 

certification testing for that design. The flared X-LITE layout reduces the effective impact angle 

to approximately 14 degrees so the impact would be less severe than the earlier test. The FHW A 

reconfirms that these three tests can be waived. 

Tangent design: 

Test 3-30 was run on the X-LITE tangent design which uses only three modified (crimped) posts. 

For this test, the 820C vehicle was offset the field side ofthe terminal to maximize the likelihood 

of the car yawing into the standard steel posts beginning with post #4. The rail height was set at 

702 millimeters (27 5/8 inches). Although all Report 350 test criteria were met, the car travelled 

over 20 meters (66 feet) behind the rail from the initial impact point and exhibited a roll angle 

slightly over 50 degrees. This post-impact trajectory again reinforces the need for a relatively 

clear and traversable runout area behind and beyond all gating terminals. Enclosure 7 is a 

summary of these test results. 

Test 3-31 was run with the rail set at its lower limit of 702 millimeters (27 5/8 inches) to verify 

its capability to stop the 2000P vehicle without override. Enclosure 8 is a summary of this 

successful test. 

Tests 3-32 and 3-33 were not run on the tangent layout for the same reason they were waived for 

the flared design. Test 3-34 and 3-35 were not run on the tangent system because these tests 

were successfully completed on the more-critical flared design and would be less severe on the 

tangent system. Test 3-39, as noted earlier, was successfully run on the stiffer X-Tension design 

during earlier testing. The FHWA agrees that these five tests can be waived for the tangent XLITE. 

Finally, your December 201

h request summarized the design changes made to the X-LITE 

terminal after your initial test 3-35 that were incorporated into the final design. The FHWA 

concurs that these modifications will not adversely affect the crash test performance ofthe first 

test and it need not be repeated.

Both systems described above and detailed in the enclosed drawings are acceptable for use on 

the NHS under the range of conditions tested, when such use is acceptable to a highway agency. 

Please note the following standard provisions that apply to FHW A letters of acceptance: 

• 	 This letter includes an AASHTO/ARTBA/AGC Task Force 13 designation that should be 

used when drafting new or revised Task Force 13 drawings. 

• 	 This acceptance is limited to the crashworthiness characteristics of the systems and does 

not cover their structural features, nor conformity with the Manual on Uniform Traffic 

Control Devices. 

• 	 Any changes that may adversely influence the crashworthiness of the system will require 

a new acceptance letter. 

• 	 Should the FHW A discover that the qualification testing was flawed, that in-service 

performance reveals unacceptable safety problems, or that the system being marketed is 

significantly different from the version that was crash tested, we reserve the right to 

modify or revoke our acceptance. 

• 	 You will be expected to supply potential users with sufficient information on design and 

installation requirements to ensure proper performance. 

• 	 You will be expected to certify to potential users that the hardware furnished has
