COURSE DESCRIPTION:

Updated in 2002, this training resulted from a partnership between the American Association of State Highway and Transportation Officials (AASHTO), the Transportation Curriculum Council (TCCC), Federal Highway Administration (FHWA), and hot-mix asphalt (HMA) industry. It was developed through the cooperative efforts of the Joint AASHTO/FHWA/Industry Training Committee on Asphalt. It combines lectures and problem-solving workshop sessions to provide participants with a working knowledge of the hot-mix asphalt construction process and equipment. The course is designed to help participants understand the effect of construction actions on the final product. This program reviews the entire HMA construction process beginning with the delivery of the HMA to the job site, through lay down and compaction, and concluding with quality control/quality assurance (QC/QA) of the completed pavement. To emphasize recommended good practice in HMA construction, various exercises are used, including troubleshooting typical field problems. The course concludes with an examination which reviews the key elements of HMA construction.

Participants are required to bring a calculator.

OUTCOMES:

Upon completion of the course, participants will be able to:

• Describe the purpose of project documents, pre-construction and pre-paving conferences, and cooperative communications on the job
• List the steps involved in preparing bases and existing pavements for overlays
• Select correct patching materials and placement techniques for pavement repair
• Define a proper HMA delivery process to the job site
• Explain the effect of the various components of a HMA paving machine on the finished mat
• Describe how to make a good longitudinal or transverse joint
• Identify QA techniques that apply to the HMA construction

TARGET AUDIENCE:

This course is designed for an audience that contains 50 percent contractor supervisory personnel and 50 percent Federal, State, and local highway agency construction engineers and field inspectors involved in the planning, construction, and review of HMA placement projects. It is important that such a mix of participants is present.
