New concrete barrier on key M5 motorway section

Contractor Tarmac has carried out major works on the UK’s M5 motorway after recycling around 30,000tonnes of concrete and providing 8,000m3 of new concrete for new slip-form central barrier works. The project, between Junctions 3 and 4a of the M5, was delivered as part of an eight-week scheme to install 13km of new concrete safety barrier. Approximately 30,000 tonnes of concrete were excavated and then crushed into Type 1 and 6F5 aggregates at Tarmac’s recycling site in Ettingshall, Wolverhampton. Over 14,0

A new section of slipformed concrete barrier has been installed on a stretch of the UK’s M5 motorway for centreline dividing protection
Contractor 2399 Tarmac has carried out major works on the UK’s M5 motorway after recycling around 30,000tonnes of concrete and providing 8,000m3 of new concrete for new slip-form central barrier works. The project, between Junctions 3 and 4a of the M5, was delivered as part of an eight-week scheme to install 13km of new concrete safety barrier.

Approximately 30,000 tonnes of concrete were excavated and then crushed into Type 1 and 6F5 aggregates at Tarmac’s recycling site in Ettingshall, Wolverhampton. Over 14,000tonnes of the recycled aggregates have already been deployed on local construction schemes.

Overnight works saw excavated material transported from the site, stockpiled locally, and reprocessed, with as many as 40 trucks bringing in around 1,700tonnes/night throughout the initiative. Night working was carried out to reduce daytime traffic congestion for road users during peak periods.

Tarmac’s Stourport depot in the West Midlands supplied the concrete for the new barrier which was constructed by Extrudakerb. Tarmac says that recycling materials helps reduce landfill needs, minimises transport and cuts carbon emissions.
According to the firm, this particular project shows its ability to handle large volumes of materials for recycling, while also using this feed to provide high quality recycled and secondary aggregates.

The company’s latest Sustainability Report reveals that, since 2004, the company has reduced waste to licensed disposal by 95%.

    The use of specialist equipment to produce hydraulically bound mixtures can save 30-40% on the cost of landfill and backfill it is claimed. The transportation and removal of old material from certain highway projects has long been a problem for contractors. But David MacLynn believes that the answer, in many instances, could lie in the use of hydraulically bound mixtures (HBM), which he says can save between 30-40% on the cost of landfill and backfill.

    Stabilisers bring recycling improvements to roads in the UK and Armenia. The local road authorities near the UK city of Bath have saved nearly €250,500 on the cost of repairing a 400m long section of the B3110 Midford Road. This saving has been achieved by opting to recycle and strengthen in-situ the existing surface, instead of using conventional full depth pavement reconstruction.
