Hot Mix Asphalt Construction
About Hot Mix Asphalt Construction
Every year, the State of California invests millions of dollars in construction of hot mixed asphalt (HMA), previously known as Asphalt Concrete (AC), pavement. Producing high quality HMA pavement requires a good partnership between Caltrans, the plant producing the HMA material and the contractor placing the HMA.
