CONCRETE & STEEL BARRIERS
Todays high speed (80-110kph, 50-70mph) road construction sites use a variety of safety barriers to improve the safety for construction workers and motorists travelling through these traffic disruptions. Safety barriers should be used where the risk to drivers, road workers, pedestrians or cyclists is higher than if there is no barrier.
The two most common types of safety barriers used on high speed construction sites are Portable Concrete Barriers (PCB’s) and 12-15m long Temporary Steel Barriers. Portable Concrete Barriers have been in use for several decades, the original designs have not changed significantly over that time.
Portable Concrete Barriers (PCB) have performed adequately across the years as safety barriers, however, they have limitations in their use. Many PCB’s remain public domain designs that have not been crash tested to the latest crash testing standards. Some barriers have passed tests with larger vehicles but are too stiff to work with smaller vehicles and have been “deemed to comply” so that industry has a solution.
