More than 1,170 tonnes of Aggregate Industries' SuperLow-Carbon asphalt has been used so far in the base and binder elements of the A590 Cross-A-Moor scheme. The £10m project includes the construction of a new roundabout, as well as link roads, to connect into the existing local road network in the Lake District. AE Yates is principal contractor. SuperLow-Carbon asphalt was specified both for its carbon-saving characteristics as well as its speed of construction. It is the first time that this type of asphalt has been used in the UK. SuperLow uses Shell's Low Carbon Bitumen in a formula that uses alternative energy sources to lower its embodied carbon footprint. It includes a biogenic material that "effectively locks CO 2 within the asphalt rather than releasing it back into the atmosphere", according to Aggregate Industries. As a warm-mix asphalt it requires less energy to produce than its hot-mix equivalent without compromising on performance, while also reducing fumes and odour.
