This article outlines the history of metal and concrete road barriers, and discusses the new European Standard for these barriers. Early types of barriers included untensioned corrugated beam (UCB) barriers made of steel, concrete safety barriers (CSBs), the wire rope safety fence (WRSF), the tensioned corrugated beam (TCB) fence, and the open box beam (OBB) fence. Increasing requirements for motorway maintenance have led to a growing demand for temporary safety barriers; in the UK, they range from plastic cones, cylinders, barrier plank systems, and water-filled systems to the most commonly used temporary vertical concrete barriers, (TVCB), consisting of large precast concrete units bolted together. For areas where work-zone protection is required, the only alternative temporary solution currently available in the UK is Varioguard, a new galvanised steel safety barrier marketed by Asset International. Almost all vehicle restraint safety systems in the UK have been tested only to level N1, covering vehicles up to 1.5t, and Varioguard is the only mobile road safety barrier tested to level H2, up to 13t. In 1998, the new BSEN 1317 Euronorm was adopted in the UK; it is based on Europewide barrier performance standards, is not product-specific, and incorporates high work-zone protection requirements. It will soon be enhanced.
