131050: Asphalt Pavement In-Place Recycling Techniques

Transportation agencies focusing on the use of sustainable, cost effective, and environmentally conscious construction practices often consider in-place recycling techniques as a viable alternative to the more traditional rehabilitation techniques used on asphalt-surfaced pavements. NHI training 131050 Asphalt Pavement In-place Recycling Techniques is designed to help participants acquire necessary skills for selecting the appropriate in-place recycling technique for a given set of conditions, choosing the appropriate materials for the project, developing suitable specifications, and constructing those projects effectively.

The Asphalt Pavement In-place Recycling Techniques course includes a brief (2hr) Web-based training (WBT) module, and two days of instructor-led, classroom-based training (ILT). Through independent study, classroom interaction, and workshop activities, participants explore the current technologies available in the area of asphalt pavement in-place recycling. The WBT lesson introduce pavement evaluation techniques and the three potential recycling techniques, along with the types of equipment commonly used for each. The classroom session focuses on project and technique selection and justification, materials considerations and mix design, construction specifications, and project control considerations during construction.

Objectives / Topics

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

  • Describe the economic, environmental, and engineered performance benefits associated with using in-place asphalt recycling
  • Identify the key factors that contribute to the selection of appropriate in-place asphalt recycling techniques under different traffic levels, pavement conditions, and environments
  • Identify the key requirements in developing effective in-place asphalt recycling construction specifications, including method specification and end-result or performance specifications
  • Demonstrate the ability to select the appropriate new materials and additives needed for each of three HMA pavement in-place recycling techniques
  • List steps that can be taken to address a variety of issues that may impact the constructability of a project
Target Audience

This course is intended for State and local transportation agency engineers, such as 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 particularly benefits those individuals responsible for selecting and designing asphalt in-place recycling projects, for writing effective specifications, or for inspecting asphalt in-place recycling projects during their construction. Contractors, consulting engineers, and industry representatives involved in asphalt pavement in-place recycling also will benefit from this course.


Complete the brief Web-based training (WBT) module prior to the classroom portion of the workshop.

Login to the NHI website ( and under Web-based Training WBT enroll and complete the following course:

1. 131050A - (Introduction to) Asphalt Pavement In-Place Recycling Techniques

It will take approximately 2 hours to complete and there is no costs. Remember that all lessons in the Web-based training must be complete in order to prepare you for the instructor-led session.
