Hampshire Highways boost for greener highways maintenance
Hampshire Highways’ ability to increase its recycling capacity, for highway maintenance operations, has been boosted with the addition of a specialist vehicle to its fleet.
A new mobile Volumetric Concrete Mixer enables concrete to be made completely from the gravel and tarmac taken from previous road repairs and for it to be delivered to work sites right across Hampshire. The mixer’s green credentials are further enhanced in that it is fuelled by low carbon hydrotreated vegetable oil (HVO) fuel.
Councillor Nick Adams-King, Executive Member for Highways Operations at Hampshire County Council, said: “We are always looking to innovate when it comes to the materials and resources used across highway maintenance activities and this is a further example of how we are striving to build in more sustainable and climate friendly methods in our operations. And it’s yet another way in which our award- winning Hampshire Highways Carbon Strategy is driving improvements towards meeting our target to be carbon neutral by 2050.”
Hampshire Highways is an established collaboration between Hampshire County Council, Milestone Infrastructure and OCL regeneration. This is the partnership behind the cutting-edge Roads Materials Recycling Facility in Micheldever – a first for Hampshire. Here, network waste, including concrete and other aggregates removed during highway repairs, are re-processed cleanly and quietly ready for re-use as road repair materials.
It is from this facility that the 100 per cent recycled raw material for the Volumetric Concrete Mixer will be supplied. Specific concrete mix designs have been created and rigorously tested to ensure they meet the quality standard and specification requirements for use across the highway network.
Stuart Gready, Managing Director at OCL Regeneration, said: “OCL is delighted to be involved in another innovation that showcases the commitment of Hampshire Highways to the decarbonisation of the network.”
As a next step, Hampshire Highways will be conducting an assessment of clinker free cement for inclusion in the concrete mix. This emits only 180 kgCO2e in its manufacture compared to 900 kgCO2e emitted by the manufacture of traditional Portland cement. This will be another effective innovative solution to combatting the impacts of climate change.
Simon Watson, Business Director at Milestone Infrastructure, said: “Milestone Infrastructure is continually looking to reduce carbon and, working with Hampshire County Council and OCL we have taken another big step forward with these innovations.”
