Asphalt Materials Plant (AMP): a plant used for the production of asphalt
Aggregate: a hard inert material of mineral composition such as sand, gravel, slag, or crushed stone
Baghouse: a filtration control system to collect dust and particulates from the air in commercial processes
Binder: residuum from the distillation of crude petroleum, or, leftover material from crude oil used as the “glue” in asphalt
Hot Mix Asphalt (HMA): aggregates and binder that are heated to above 300º Fahrenheit to form asphalt
Particulate Matter (PM): Solid particles and liquid droplets in the air.
Polycyclic Aromatic Hydrocarbons (PAHs): A class of chemicals that occur naturally in coal, crude oil, and gasoline. They result from burning coal, oil, gas, wood, garbage, and tobacco. PAHs can bind to or form small particles in the air. High heat when cooking meat and other foods will form PAHs.
Recycled Asphalt Pavement (RAP): asphalt pavement that has been broken up and recycled into useable aggregate material
Recycled Asphalt Shingles (RAS): asphalt shingles that have been broken down and recycled into useable aggregate material
Volatile organic compounds (VOC): compounds that have high vapor pressure and low water solubility that are emitted into the air from products or processes
