Miles Macadam recently completed the second phase of a resurfacing programme in partnership with Luton Borough Council. Luton aim to be a net zero town by 2040, ten years ahead of the national target. To reduce construction emissions, the council adopted a whole life carbon approach when selecting suppliers. Miles Macadam was chosen for its durable, low-carbon materials, supporting this goal. Luton has used Miles Macadam’s low-carbon Milepave™ grouted macadam in its maintenance programme for several years and, after a successful 2023 trial of the new zero-carbon material Bioseal™, they decided to extend the trial into 2024 in addition to their standard Milepave™ maintenance programme.

The programme featured of variety roads across Luton, some were overlayed with Miles Macadam’s Milepave™ which provides a 35% saving in carbon emissions compared to traditional materials due to its lower resource consumption, reduced bitumen content, and more energy-efficient manufacturing process. To further minimise the carbon footprint, the remaining roads in the programme, Barton Road and Birdsfoot Lane, were resurfaced using Bioseal™, a biogenically modified asphaltic grout. This biogenic material acts as a Carbon Capture and Storage (CCS) vessel, permanently sequestering carbon within the road surface.

Delivered Programme of Work:

  • 22,078m² of surfacing
  • 35 tCO₂e total emissions

Environmental Saving:

  • Savings of 239.33 tonnes in aggregates and 33 tonnes in straight run bitumen over conventional materials
  • Milepave™ saved 35% in carbon emissions in comparison to a traditional surfacing material and a non-carbon neutral surfacing contractor
  • Additional sites utilising Bioseal™ saved a further 21% in carbon emissions
  • Increased performance and subsequent lower whole life carbon costs

Financial Saving:

  • Designed system to last longer, address specific issues and ensure lower whole life cost
