Three

strand

cable barriers were first developed in the 1960’s and found to have several desirable

characteristics as compared to other roadside barriers such as guard rail

.

Brifen Wire Rope Safety Fence is

a four strand woven wire rope intended to prevent vehicles f

rom veering off a road. This experimental

feature is manufactured by Brifen USA Inc. and adheres to NCHRP 350 test level three. This designation

implies that the product can withstand the impact of a vehicle traveling at 60 mph. The purpose of this

inve

stigation was to evaluate the woven rope system in comparison to a more widely used three wire rope

cable barrier. Comparatively, the four stand woven wire rope is marketed to provide enhanced levels of

safety while providing substantial reductions in ins

tallation, maintenance and repair costs.

The Brifen system required an increased level of effort during initial installation when compared with

a standard three

-

cable wire rope fence

.

The resulting system appeared to be stronger, with less deflection

in

the cable along its entire length

.

The initial installation encountered no difficulties, as observed by

Construction, Operations or Research staff.

Through site observations conducted by Materials and Research personnel it appears that the

safety fence is

performing considerably well, however the posts under torque is causing concern of how well

the fence will continue to work when vehicles make contact with it. The excluder caps, post caps, and

locator pegs should be replaced with a more durable material

due to excessive cracking and breaking. This

fence might not be an ideal choice for Vermont due to the inclement weather and the involved tasks of

repairing the fence after accidents. Operations have claimed that the repair p

rocess is quite extensive
