Aggregate Industries has completed a trial of its new Foamix product, which it said paves the way for 'carbon-negative' asphalt.
The materials supplier said the new Foamix cold recycled bitumen-bound material is manufactured with negative carbon aggregates and biogenic bitumen throughout.
The firm announced that a trial on the M65 slip road in partnership with Lancashire County Council has delivered an asphalt solution with net zero cradle to gate embodied carbon emissions (Scope A1-A3), without the use of carbon offsetting, thanks to the new product mix and use of onsite mobile plant production and installation.
Aggregate Industries said its achievement aligns with its commitment to increase the use of Recycled Asphalt Pavement (RAP) by 60% in asphalt products, adding that it is possible to achieve a negative carbon footprint on projects when reusing the planings onsite.
Aggregate Industries Surfacing Solutions managing director Thomas Edgcumbe said: ‘This sets a new standard for sustainable construction materials, with the use of onsite production and high percentage of RAP, allowing us to build a circular economy.’
Lancashire County Council highways asset manager Paul Binks said: ‘As part of our ongoing drive to reduce carbon across our highway network; recycling of our existing roads back into new roads has always been one of our main drivers.
‘The Foamix supplied by Aggregate Industries is being used successfully throughout the county and this latest innovation is the next generation, which will see a further reduction of carbon emissions across the network.’
Aggregate Industries said Foamix Eco can be used in conjunction with its SuperLow Carbon asphalt to deliver an ultra-low carbon pavement.
