Warm mix solution getting traffic moving quickly


“With carbon reduction at the centre of the Government’s Construction Strategy and many local authorities working to achieve net zero targets by 2030, warm mix asphalt is a proven materials technology that benefits road users, residents living around areas of roadworks, highways workforce who spend less time exposed to traffic during roadworks, and the environment.”

Brian Kent, national technical director

This year we have been calling on local authorities to adopt new thinking in road building and repair to help get Britain’s roads moving more quickly. The solution involves laying asphalt at lower temperatures, ‘warm-mix asphalt’, rather than traditional mixes which means it can be laid faster, sets quicker and is much more sustainable to produce. And best of all it enables roads to reopen more quickly, getting traffic back on the move, something that will be increasingly important as people start to travel again.


Tarmac’s ULTILOW warm mix asphalt is quick and easy to lay and requires less cooling time between courses, increasing the amount of material that can be laid in a standard shift – saving time and money. It’s estimated that this method of road building and repair could save 60,000 tonnes of CO2 per year nationally, the equivalent of 300 million miles of car journeys and offers significant public health benefits in terms of clean air. The UK is lagging behind other countries in adopting warm mix asphalt which is currently at less than four percent, far behind the US (40 percent) and France (15 percent).

Brian Kent, national technical director, said: “As we begin our road to recovery from the COVID-19 pandemic, it’s never been more important for the construction industry to work together with local authorities and councils to adopt more sustainable ways of working.
