Hot Mix Asphalt (HMA) is a type of asphalt concrete used primarily for paving roads, parking lots, and airport runways. It is made by mixing aggregates, such as sand and gravel, with a binder, typically asphalt cement, at high temperatures. This process ensures that the materials are workable and can be easily spread and compacted. Once applied, HMA cools and hardens, creating a durable surface that can withstand heavy traffic and various weather conditions. Its flexibility allows for minor adjustments during installation, making it a popular choice in the construction industry for creating smooth and long-lasting pavements.
