Description

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.
