The use of recycled materials in asphalt pavement construction is supported by the Federal Highway Administration (FHWA) and other transportation organizations for a number of reasons. First, recycling asphalt pavements is often more cost-effective than more traditional rehabilitation and reconstruction alternatives, which is important in today's economic climate. Second, when designed and constructed effectively, these pavements perform well under arange of traffic levels and environmental conditions. Finally, recycling provides sustainable, environmental benefits, e.g., a reduced carbon footprint,the preservation of natural resources, and the reuse of high-quality aggregates contained within the existing pavement.

Transportation agencies focusing on the use of sustainable,cost effective, and environmentally friendly construction practices must consider recycling techniques as a viable alternative to the more traditional rehabilitation techniques used on asphalt-surfaced pavements. However,increased guidance is needed on selecting the appropriate recycling technique for a given set of conditions, choosing the appropriate materials for the project, developing suitable specifications, and constructing those projects effectively. This course presents the current technology available in the asphalt pavement recycling area and provides the guidance necessary fortransportation agencies to use and construct those techniques effectively.

The course is taught as a 2-day instructor-led training course focusing on project and technique selection and justification, material considerations and mix design, construction specifications, and project control considerations during construction.

There is also a web-based training (WBT) independent study that serves as a prerequisite to the instructor-led course. It takes approximately 1.5-hours to complete. The WBT introduces the pavement evaluation techniques commonly used to determine the cause and extent of pavement deterioration present in a pavement section that is a candidate for asphalt recycling. The material introduces common asphalt pavement distress types and identifies methods of assessing pavement condition, i.e., pavement condition surveys, nondestructive testing, and coring. The WBT also introduces the three recycling techniques listed below and the types of equipment commonly used for each process.

Hot in-place recycling (HIR)

Cold recycling (CR)

Full depth reclamation (FDR)

The material also discusses the use of cold milling onin-place recycling projects.


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

  • Describe the economic, environmental, and engineered performance benefits associated with using recycling.
  • Identify the key factors that contribute to the selection of appropriate asphalt recycling techniques under different traffic levels, pavement conditions, and environments.
  • Identify the key requirements in developing effective recycling construction specifications including method specification, warranty, and end result or performance specifications.
  • Demonstrate the ability to select the appropriate new materials, e.g., binders and aggregates, and additives needed for each of the three asphalt recycling techniques.
  • List steps that can be taken to address a variety of issues that may impact the constructability of a project.
  • Each lesson has enabling learning outcomes that support each terminal learning outcome.


This course is designed for state and local transportation agency engineers, e.g., pavement managers and maintenance engineers, and other agency personnel who are responsible for selecting, designing, or constructing the agency's asphalt pavement maintenance, resurfacing, rehabilitation, and reconstruction alternatives. The course will particularly benefit individuals responsible for selecting and designing asphalt recycling projects, for writing effective specifications, or for inspecting asphalt recycling projects during their construction. Contractors, consulting engineers, and industry representatives involved in asphalt pavement recycling will also benefit from the course.
