Safety barrier of in situ concrete

A safety barrier of in situ concrete is a concrete element poured on site, situated along the road or mainly in the central reservation with the aim of guiding an errant vehicle in the safest possible way.

On-site pouring is done by means of a slipform machine that compacts the ready-mixed concrete and converts it into a finished product by means of an appropriate mould.

In the past the ‘Jersey’ profile was often used, nowadays it is the ‘Step Barrier’ profile.

• In situ concrete safety barriers are constructed along the road or often in the central reservation.
• They provide retaining capacity depending on the type of vehicle to be retained. This ranges from a light passenger vehicle to a 38-tonne truck.

• Checks whether the necessary crash tests have been carried out in accordance with PTV 869.
• Random sample-based inspections on site to monitor whether a concrete mixture is delivered in accordance with PTV 850.
• Random sample-based inspections at the site to check whether the correct reinforcement strands are being used.
• Random sample-based inspections at the certificate holder’s site to monitor the traceability of the reinforcement strands.

A durable identification label is affixed to the product by the installer after installation, stating the BENOR mark and the 8-digit quick code. Using this code, the product sheet can be found on extranet.copro.eu.

• Type testing of the products conforms to European test standards and PTV 869.
• The shock index of a certified product is always at least ASI B.
• A check is done to determine whether a concrete mixture is being supplied in accordance with PTV 850.
• A check is done to determine whether the correct reinforcement strands are being used.
• The traceability of the reinforcement strands used is monitored. Traceability is guaranteed by the product’s certificate holder.
