The Astec warm mix system enables Astec’s worldwide network of existing and new plant owners, who are all experiencing rising fuel and liquid asphalt prices, to lower their overall operating costs without sacrificing quality.
The system is said to allow producers to reduce fuel consumption, increase production, eliminate smoke and smell and use a higher percentage of recycle by producing mix at a lower temperature.
Astec says it does not require the addition of expensive commercial additives, but instead water is injected into the mix along with the liquid asphalt cement. The injection of water causes the liquid asphalt to foam and expand in volume, which helps the liquid asphalt coat the aggregate at a lower temperature.
“The Astec warm mix system can be installed on either existing or new Aastec drums, and it can also be retrofitted to continuous mix and batch plants from any manufacturer.
