    摘要： Methods and systems for producing warm foam mix asphalt are disclosed. In some embodiments, the methods include the following: injecting an ethanol additive into asphalt binder having a temperature below the auto ignition point of ethanol to form a foamed asphalt stream; adding the foamed asphalt stream to a mixing zone; adding at least one of aggregate and reclaimed asphalt pavement to the mixing zone; adding a foaming agent to the mixing chamber; heating at least one of the mixing zone and the at least one of aggregate and reclaimed asphalt pavement; mixing the foamed asphalt stream and the at least one of aggregate and reclaimed asphalt pavement to form a warm foam mix asphalt; collecting emissions from the mixing zone, the emissions including ethanol vapors; and recycling the emissions to the mixing zone.
