Improving and Developing Pavement Design Inputs and Performance Functions for Cold Recycled Pavement Layers in Minnesota

Status:  Complete
Report Date:  02/17/2026

Summary:

Recycling asphalt pavements is a strategy used by transportation agencies to reduce road construction costs and increase sustainable practices. But engineers often don’t have a complete performance characterization of the recycled material, which can lead to overdesigned pavement structures. This project developed tools and methodologies to better understand the engineering characteristics and capabilities of the recycled materials to ensure the structural integrity and long-term performance of newly constructed roads without costly overdesigns.
