The UK equivalent is the concrete step barrier. [citation needed] First tested in 1968 by the then Department of Highways in Ontario, Canada, the Ontario Tall Wall is a variant of the Jersey barrier. [10] Standing at 42 inches (107 cm), it is 10 inches (25 cm) taller than the standard Jersey barrier.
The F-shape barrier is a concrete crash barrier, originally designed to divide lanes of traffic on a highway. It is a modification of the widely used Jersey barrier design, and is generally considered safer. [1] A parametric study, one that systematically varies the parameters, was done through computer simulations of barrier profiles labeled A ...
Following the September 11 attacks, at the Hanford Site's Plutonium Finishing Plant, eco-blocks and Jersey barriers were used to create a 1.5-mile (2.4 km) barrier against vehicular attack. [4] The Seattle Police Department used eco-blocks to construct walls around their East Precinct building while the Capitol Hill Organized Protest was ...
An early concrete barrier design was developed by the New Jersey State Highway Department. This led to the term Jersey barrier being used as a generic term, although technically it applies to a specific shape of concrete barrier. Other types include constant-slope barriers, concrete step barriers, and F-shape barriers.
A barrier transfer machine, also known as zipper machine or road zipper, is a type of heavy vehicle that is used to transfer concrete lane dividers, such as Jersey barriers, in order to relieve traffic congestion during rush hours. Many other cities use them temporarily during construction work.
Damage to Bremer wall concrete barriers in Afghanistan, 2012. During the Iraq war, US forces found concrete to be their most effective weapon to reduce violence and protect the local population from sectarian violence while impeding the movement of insurgents. At an average cost of $600 per wall in the mid-2000s, billions of dollars were spent ...
Products include: box culverts, 3-sided culverts, bridge systems, railroad crossings, railroad ties, sound walls/barriers, Jersey barriers, tunnel segments, concrete barriers, TVCBs, central reservation barriers, bollards, and other transportation products. Precast concrete can also be used to make underpasses, surface crossings, and pedestrian ...
The failure ... was due to the inadequate capacity of the lateral load resisting system, which was comprised of guy lines connected to concrete "Jersey barrier" ballast. [6] The concrete barriers used as anchors for the guy lines were not fixed in place; they resisted loading only by friction with the ground and through their own weight—about ...
