Overview

Airfield asphalt pavements present unique performance challenges as compared to highway pavements. Airfield pavements are subjected to significantly heavier loadings, higher tire pressures, and overall require a higher level of performance as compared to a highway pavement. Due to these differences, construction requirements for airfield asphalt pavement projects can be quite different than those of highway pavement projects, and consequently their specifications and materials requirements are also different. This course is designed for technicians who are involved in sampling and testing aggregate materials and asphalt mixtures that are used in airfield pavement construction.

Program Content

This course consists of interactive lectures, demonstrations, and hands-on training of fundamental aggregate and asphalt mixture tests used during asphalt mixture production. The course will be split between classroom lectures and hands-on work using the testing equipment in the laboratory. The course will provide engineers, technicians and testing personnel with an understanding of the sampling and testing requirements associated with airfield asphalt mixture production and construction. Approximately 1 1/2 days will be spent in the classroom and 1 1/2 days will be spent in the laboratory. A brief outline of the course follows.

Goals and Objectives

This 3 1/2-day course will provide a basic understanding of the materials and tests that are involved in the design and production of asphalt mixtures. In addition to classroom instruction, this course will also provide hands-on laboratory training using the laboratory tests involved in the design and testing of asphalt mixtures.

Materials

Each participant will be provided a book of the instructional material.

Examination

In order to obtain a certification as an Airfield Asphalt Lab Technician, each participant must take a three-hour exam and obtain a minimum score of 70%.

Eligibility

Applicants must have either 1) three years of asphalt laboratory experience or 2) a two-year engineering-related education and one year of asphalt laboratory experience to attend this course. Applicants must provide documentation that these requirements are met prior to attending the course.

Continuing Education Credits

The course will provide 2.4 CEUs or 24 Professional Development Hours.

Location

This course will be located at the National Center for Asphalt Technology's main research facility in Auburn, Alabama.

Fees, Refunds, and Deadline

The registration fee of $1540 includes the training program and all course materials. Costs for housing, food and transportation are the responsibility of each participant. Prepayment and registration must be received no later than ten days prior to the start date of the course. Cancellations received at least ten days prior to the course start date will result in a full refund.
