Reclamation and Recycling Techniques to Achieve Perpetual Pavement Characteristics

Status: Developing RFP

Objective

The objective of this project is to identify and apply the proper treatment for Stabilized Full-Depth Reclamation (SFDR) test sections constructed at MnROAD in 2008. The proper treatment will extend the good performance and continue perpetual pavement behavior of MnROAD cells 2 and 3. MnROAD cells 4 and 15 need a deeper rehabilitation and have additional challenges from the original full-depth asphalt structure. It is proposed that cells 4 and 15 be designed and constructed to be a Perpetual Pavement (PP) achieved using reclamation and recycling techniques. The use of reclamation and recycling techniques to achieve perpetual pavements is gaining traction with agencies around the US due to the sustainability benefits of reclamation in addition to the sustainability benefits from a long life pavement.

Historically, these sections at MnROAD have been used to promote benefits of reclamation and can continue to serve as an example of effective, long-lasting SFDR. The research will also address rehabilitation techniques for full-depth asphalt pavements using modern techniques and materials.

Specifically, the NRRA research contract is requested for this project to:

  1. Develop solutions for FDR pavements after ≈15 years from construction - Preventive Maintenance and Rehabilitation;
  2. Develop layer coefficients or other design inputs for recycled / reclaimed layers;
  3. Develop solutions for full-depth asphalt pavement rehabilitation; and
  4. Conduct structural analysis to characterize pavement responses and performance from a perpetual pavement design perspective.
