Energy efficient asphalt could drive down road emissions

Energy efficient asphalt could drive down road emissions

Using lower temperature asphalt in road construction could save the UK road industry more than £46m over the next 10 years, while also cutting carbon emissions arising from the process by up to 39 percent, a new study has found.

A three year project by Lafarge Tarmac and the Carbon Trust claims to have successfully trialled a material that bonds road materials as effectively as conventional methods, but uses temperatures much lower than the standard 180C and 190C meaning that it requires far less energy.

The project team calculates that should the UK road industry adopt the specifications for the use of the new asphalt that they have designed then the technology could account for 21 percent of the total market within 10 years. Such a market share could save the industry £46.2m and cut emissions by around 260,000 tonnes of CO2 over the decade ? equivalent carbon savings to taking more than 345,000 cars off the road.
