With the ever-increasing focus on carbon reduction, the technical teams at Aggregate Industries have worked hard to create the UK’s first ever carbon neutral asphalt. But how did they do it?
Following its parent company LafargeHolcim becoming the first construction materials company to sign the Net Zero Pledge and the recent launch of its ECOPact low carbon concrete, this is the latest in a series of steps taken towards more sustainable materials by Aggregate Industries.
As an established brand in the Aggregate Industries, SuperLow features reduced carbon levels when compared to standard asphalt as it is manufactured at reduced temperatures.
Aggregate Industries reduces the embodied carbon footprint of the companies asphalts with three actions: improving production processes, using alternative energy sources, and mixing at reduced temperatures.
So, by choosing SuperLow, you’re automatically saving up to 17% carbon, with reduced emissions due to a number of energy-saving measures and Aggregate’s decarbonisation scheme. Plus, SuperLow has up to 40% reduction in energy consumption compared to standard asphalt.
By optimising Aggregate Industries’ production processes every step of the way, construction is being made much more sustainable, all without any change to product performance.
Why choose SuperLow?
The top five reasons:
By taking less energy to manufacture than conventional asphalt, SuperLow gives a lower carbon footprint, through decarbonisation with accredited partners.
With quicker, cheaper, project completion, SuperLow asphalt reaches trafficking temperatures quicker than conventional hot asphalt, which means an earlier reopening of carriageways to the travelling public, with less traffic disruption.
Lower asphalt temperatures during production reduces binder ageing and enhances in-service life expectancy
Lower asphalt temperatures reduce nuisance fuming and steam at the project site which can impact on visibility.
Same great quality
Even at lower temperatures SuperLow asphalt remains highly compactable for longer, allowing more time for full compaction and delivering enhanced performance and durability.
With the mix requiring lower temperatures than traditional asphalts, SuperLow also cools to trafficking temperature quicker, meaning repairs and resurfacing take less time. The cooler temperature also reduces binder ageing.
The recently launched SuperLow range of asphalts used in conjunction with decarbonisation solutions - is the only carbon neutral asphalt solution available in the UK market at present. SuperLow is manufactured at lower temperatures to help reduce carbon levels when compared with the mixing of standard asphalt.
