About
This is a course developed by the Federal Highway Administration (FHWA). The entire class should take approximately 4.5 hours to complete. Asphalt concrete is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the 20th century. The correct asphalt mixture can provide a number of benefits for a road, such as resistance to permanent deformation, fatigue cracking, low temperature cracking, and moisture; durability; and good surface texture. As you’ll learn in this training, the objective of the mixture design process is to select an aggregate gradation and binder content (with or without modifiers) to achieve these properties so that pavements last longer. This course will review the characteristics and engineering properties of asphalt mixtures and their effects when utilized in highway applications, as well as the overall mix design concepts and how construction operations can affect the ultimate performance of asphalt mixture pavements. This course is intended for a variety of positions within local agencies and tribal governments, with an emphasis on the role of the materials engineer, as well as anyone involved in the mix design, placement, or rehabilitation of asphalt pavement. Training includes: 1. Asphalt Mixtures 2. Asphalt Binders and Selection 3. Design Concepts 4. Production, Delivery, and Placement 5. Quality Assurance and Acceptance This course is hosted on an outside platform. If you have issues accessing the class, please contact FHWA. After completing the course, you will receive a certificate from FHWA. You will need to submit that certificate to us using the form contained within this class for credit. The course can be counted for Road Scholar II credit as a substitute for Introduction to Asphalt Technology.
