Evaluation of Stabilized Full Depth Reclamation (SFDR)

Summary:

Researchers found that stabilized full-depth reclamation (SFDR) produces stronger roads for commercial loads and mitigates cracking in Minnesota. The method also shows promise for uses in rural agricultural areas. How much greater the strength gained with each stabilizing agent is better understood, though still not conclusively. Generally, SFDR offers a 50 percent improvement in pavement base strength while fully recycling old pavements.

Final Deliverables:

• Field Investigation of Stabilized Full-Depth Reclamation (SFDR) (Report #2018-33)
