Miles Macadam recently delivered the First Carbon Capture and Storage Surfacing Scheme in South Wales in collaboration with Cardiff Council and Steelphalt as part of Cardiff’s vision for a Carbon Neutral City by 2030. For several years, Cardiff Council have been utilising lower carbon and lower resource materials by specifying Miles Macadam’s reduced carbon product Milepave™. The latest trial on College Road trial has advanced Milepave’s sustainability by incorporating Biochar into both the receiving course and grout. This captures carbon within the road surface, preventing its release into the environment and reducing climate impact

Delivered Programme of Work:

  • 3,525m² of surfacing
  • 321 tonnes of Milepave, using steel slag aggregate
  • 8.75 tCO₂e total emissions, including installation (19.86 tCO₂e for a conventional surface course)

Environmental Saving:

  • Savings of 293 tonnes in virgin aggregate and 4 tonnes of straight run bitumen over a conventional material
  • 9.66 tCO₂e captured in Biochar and stored in the Biopave™ surface course
  • Increased performance and subsequent lower whole life carbon costs
