The use of warm mix asphalts (WMAs) cut CO2 emissions by around 15% and, importantly, can be used to produce a number of different products with recycled or secondary content as well as those that offer increased durability, enhancing these savings.
While hot mix asphalt, produced at temperatures in excess of 160°C, is currently the default asphalt type specified in the UK, this is changing with National Highways now encouraging the use of WMAs as standard on the strategic road network.
Our ERA warm mix process can be used to produce a wide range of asphalts and offers a number of additional benefits including:
- Faster setting times
- Increased durability through reduced oxidation
- Reduced steam production in wet weather
- Reduced odour on site
- Improves adhesion as both liquid antistrip and warm mix additive
- Less fumes: a 10°C reduction in mix temperature reduces fuming by ~50%
