Warm mix asphalt
We have made the switch!
Aggregate Industries is driving forward with the commitment towards Net Zero. Moving our asphalt production from hot mix to warm mix.
What is warm mix asphalt (WMA)?
Mixed at temperatures 20°- 40°C lower than hot mix asphalt (HMA), warm mix asphalt provides a more sustainable solution for road applications.
All base and binder material is now produced as warm mix as standard. In addition Aggregate Industries has attained BBA certification for our SHW Clause 942 materials as a warm mix, and many of our performance asphalt products can also be manufactured as warm mix.
How does it work? Through the use of additives and innovative technology, we’ve tested our range of asphalt products to ensure they still meet national specifications, including National Highways standard (SHW clause 908). Warm mix asphalt reduces CO2 emissions by using less fossil fuels and resources during the manufacturing process.

Environmental benefits of using warm mix asphalt, include:
- carbon reduction
- reduced project costs
- enhanced life-expectancy
- …with the same high quality and performance when compared to hot mix.
On-site benefits:
- reduced nuisance fuming
- minimal odour and steam at the project site
- safer working conditions at both the plant and site
