Solihull-based building materials specialist Lafarge Tarmac and the Carbon Trust have identified a new low-energy method for road building which could save the taxpayer millions of pounds following an intensive three-year research project.

The low temperature asphalt project has the potential to save the UK road industry £46.2 million in energy costs over the next decade as well as cutting carbon emissions by up to 39 per cent.

Low temperature technology can help reduce the duration of works on road schemes with potential safety benefits for both the travelling public and the workforce, especially on large-scale infrastructure projects. Already, the West Midlands Highway Alliance, representing 14 local authorities, has committed to use the new method to help reduce its CO2 emissions by 20 per cent by 2015.

The trial has enabled the project team to accelerate the production and adoption of lower temperature asphalts. The project was led by Lafarge Tarmac and the Carbon Trust within its Industrial Energy Efficiency Accelerator programme.

Funding came from Lafarge Tarmac and the Carbon Trust, via the Department of Energy & Climate Change and support from the Department for Business Innovation and Skills.

Martin Riley, managing director for Lafarge Tarmac’s asphalt and aggregates business, said: “As a leader in sustainable construction solutions, we want to use our expertise to help bring these solutions to our clients and customers.

“This project with the Carbon Trust will help unlock barriers to bring lower temperature asphalt into wider use, cutting energy use, reducing CO2 emissions and enabling us to deliver projects more quickly for clients.”
