As a multi-award winning manufacturer and supplier of concrete roadside safety barriers, Hardstaff was appointed by National Highways contractor, Barrier Services, to provide a suitable safety barrier system for this scheme.
The REBLOC RB84XEAL_8 permanent precast concrete vehicle restraint system (VRS) was installed along the 6.5km stretch, protecting road users from barrier breakthroughs along the busy route.
Tested to European Standard EN1317, the embedded system has a high containment performance class of H2 and can safely contain and redirect the impact of a 13-tonne bus travelling at 80km/h (50 mph) and impacting at 20 degrees.
The REBLOC system forms a high strength continuous chain of barrier that provides high containment and safely transfers energy and impact forces.
The system was also installed with integrated drainage channels, allowing water to drain through the barrier.
REBLOC RB84XEAL_8 was the ideal option for this project, with the ability to deviate around and protect existing structures in place on the M5 central reserve, and to serve as a foundation for matrix signs.
The barrier was also easily connected to an existing steel barrier in place at the end of the system, making the REBLOC RB84XEAL_8 a highly adaptable and flexible choice.
For added safety, two Steel Step Barriers were installed on the route providing emergency crossing points in the central reserve barriers.
The system consists of a rapid opening and closing bi-directional gate. With its extremely low deflection and high containment capability, the Steel Step Barrier is the ideal system for emergency access points between concrete barrier systems.
As concrete barrier experts, Hardstaff was an integral part of the Highways England and Barrier Services team throughout the project, and was invited to take part in collaborative meetings that took place during the scheme.
