With Warm Mix Asphalt energy will be saved and CO2 emissions will be reduced.
A temperature reduction of 30 degrees yields savings of 9 kWh of energy per ton of asphalt mix produced. This corresponds to 0.9 litres of heating oil per ton of asphalt mix. Accordingly, CO2 emissions also drop.
When using these asphalts at moderate or no temperature reductions their compactability improves significantly. This is especially advantageous when asphalts have to be laid by hand or during adverse weather conditions. The targeted degree of compaction can be achieved without fail and it is easier to lay thin layers.
