Workzone Barriers also known as Temporary Barriers or Portable Barriers are designed to shield worksites located adjacent to roadways.

Workzone Barriers are used as part of the traffic management plan to protect roadside workers and guide motorists through the construction zone. Workzone Barriers are typically classified as plastic, steel or concrete and are designed for rapid deployment and removal.

Workzone barriers are a longitudinal safety barrier system comprising a length-of-need section and end terminal. The designer should consider the road pavement type, clearance between the barrier and workzone and the posted speed through the construction area when selecting the most appropriate workzone safety barrier system.

Workzone Barriers FAQs

What are the different types of workzone barriers?

Workzone Barriers are typically available as three (3) types: Concrete, Steel and Plastic.

How do I decide when to use a concrete, steel or plastic workzone barrier?

The selection of a workzone barrier should consider the following:

  • The available space between the position of the workzone barrier and worksite.
  • The type of road pavement where the workzone barrier will be positioned.
  • The speed of vehicles passing through the construction area.

What is the term ‘pinning’ when referring to workzone barriers?

The pinning or anchoring of a workzone barrier stiffens the crash barrier system reducing the dynamic deflection during a vehicle collision.  This is an important consideration for constrained sites with limited space between the workzone barrier and the location of roadside workers.

What is the evaluation criteria for the assessment of workzone barriers?

Similar to permanent barriers, such as guardrails, workzone barriers are evaluated through full-scale crash testing. MASH is the basis of crash testing as nominated by the Austroads Safety Barrier Assessment Panel (ASBAP).
