Warm mix asphalt production using ethanol
- Summary
- Asphalt is a widely-used material for road construction and can also function as a sealant material. Traditional asphalt production requires high-temperature heating of the asphalt blend to reduce viscosity and achieve thorough mixing. In recent years, a new class of asphalt called warm mix asphalt has been developed which uses mixture additives to reduce the required production temperature, allowing for better workability and reduced greenhouse emissions. While most warm asphalt techniques employ water-based additives, this technology uses an ethanol mixture as a mixing solvent to further reduce the temperature needed to mix the asphalt, minimizing the risk for moisture trapping in the asphalt that may lead to structural problems in the long term.
