Hot Mix Asphalt Construction

About Hot Mix Asphalt Construction

Every year, 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. Caltrans has recently updated and retitled Standard Specification Section 39 “Asphalt Concrete,” to Section 39 “Hot Mix Asphalt. ” Section 39, “Hot Mix Asphalt,” of the Standard Specifications is an amendment to the special provisions of all contracts currently awarded by Caltrans. The 12 standard special provisions for Hot Mix Asphalt and updated Section 39 HMA incorporated portions of some of the 35 existing standard special provisions related to Asphaltic paving materials.
