PRODUCT DESCRIPTION 

r. New Hardware or (' Modification to 

• Slgnl0c<1nt Modification Existing Hardware 

For Standard System (anchored at ends only): 

Zoneguard was tested to NCH RP Report 350TL-3,TL·4 and MASH TL-3 In 2007 and received ellglblllty 

lettersS· 176 and B- I76A In 2008. At the time two different anchoring configurations were tested. This request 

pertains to the configuration which was anchored at each end of the run and which we call our "Standard 

Anchoring Configuration'. The orlglnal tests used to establlsh MASH ellglblllty were ZG·USA· \ and ZG·USA·S. 

Data summary sheets for both are attached. In these original tests the surface was concrete and the anchors 

used were a combination of adhesive anchors and 12" long pins. The recent testing performed and submllled 

herein was on both asphalt irnd concrete. The attached document describes some minor modifications made 

to the barrier, the most slgnlncant being the removal of the rubber pads on the boll om of the barller. With this 

request we seek approval of the modified system without the rubber pads on both asphalt and concrete 

surfaces. 

CRASH TESTING 

lly signature below, the Engineer afnllated with the testing laboratory, agrees In support of this submission that 

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

criteria. The Engineer has determined that no othl!r crash tests arl! necessary to dl!t<?rniine the d<?vlcl! mc<?ts

Required Test Narrative Evaluation 

Number Description Results 

Test ZG-USA-1 performed previously. For 

this barrier system, MASH Test 3-10 (2425-lb 

small car) was not tested because the small 

car test is not the controlling test for the 

strength of the barrier system and vehicle 

stability. MASH Test 3-11 (5000-lb pickup 

truck) is the controlling test for strength of 

the barrier system for Test Level 3. Due to 

the heavier vehicle mass for the pickup, 

MASH Test 3-11 produced higher impact 

energy and resulted In a greater force 

applied to the barrier units and 

connections. The center of gravity (e.g.) of 

the pickup truck is higher than the center of 

3-10 (11 OOC) gravity of the small car. As a result, vehicle Non-Critical, not conducted 

stability is of greater concern for this barrier 

type for the pickup truck test. If vehicle 

stability and strength of the barrier system 

are acceptable for the pickup truck test, it is 

the assumption ofTII that these evaluation 

parameters will be acceptable for the small 

car test. The MASH small car presents a 

lower center of gravity and smaller 

impacting force on the barrier system. In 

addition, lateral deformations in the barrier 

system from the impacting vehicle and the 

forces in the anchoring hardware to the 

deck are expected to be greater for the 

pickup truck test.
