Warm mix asphalts offer big savings in carbon emissions, but the UK is still way behind the US in the use of this technology.
Despite over 300 local authorities declaring a climate emergency in 2019 and Warm Mix Asphalt getting the backing of The All Party Parliamentary Group [APPG] on Highways in their ‘Working for Better Roads’ a report, warm mix asphalt still represents just 5-6% of asphalt volumes in the UK. This compares to almost 50% in the United States.
Warm mix asphalts generally support carbon dioxide savings of between 8 to 12% depending on plant efficiency and there is no compromise on performance. Using the figures from the report; if all asphalt production in Great Britain in 2017 had been switched to WMA, it would have saved at least 61,000 tonnes of CO2 – the equivalent of cutting almost 300 million miles of car journeys.
