HMA (Hot Mix Asphalt)

Hot Mix Asphalt (HMA) is a common material used to pave roads and highways. It consists of a precise blend of asphalt binder (a sticky, black substance), crushed stone, sand, and gravel. When heated, these ingredients are mixed thoroughly, creating a malleable material that can be laid down smoothly. Once cooled, HMA hardens into a durable, weather-resistant surface that provides a smooth driving experience. Its flexibility helps accommodate traffic movement and temperature changes, making it an effective choice for roadway construction and maintenance.
