DESCRIPTION:
This training course is the result of a partnership between the American Association of State Highway and Transportation Officials (AASHTO), Federal Highway Association (FHWA), and hot-mix asphalt (HMA) industry. It was developed through the cooperative efforts of the Joint AASHTO/FHWA/Industry Committee on Asphalt. It combines lectures and problem-solving workshop sessions to provide participants with a working knowledge of hot-mix asphalt materials, their characteristics, and controls. The course focuses on two areas. The first provides technical information on the material properties of HMA, the processes used to measure these properties, and the effect that these properties have on the final, compacted pavement. The second involves achieving these properties in the field, with discussions on quality management and analyzing the impact of segregation and density on HMA pavement performance. The course concludes with an examination that reviews the key elements of HMA materials, characteristics, and control.

• Identify the various and desirable properties of asphalt, aggregates, and mixtures
• Describe the proper procedures for handling, storing, sampling, and testing the materials
• Distinguish between desirable and undesirable results of tests used for controlling and analyzing the quality of HMA
• Select the processes and procedures that assure the quality of HMA pavements

TARGET AUDIENCE:
Contractor personnel at both the production facility and on the pavement lay down site, owner/agency personnel involved with the inspection of HMA pavement construction, and others directly involved in the production and construction of hot-mix asphalt pavements. The course is designed for an audience that is a mix of contractor personnel and Federal, State, and local highway agency personnel.
