Illinois Flexible Pavement Design and Monitoring

Design procedures and policies for flexible (asphalt) pavements are continually evolving. This project, building off R27-233, will evaluate the Illinois Department of Transportation’s current design method and policy documents in terms of dynamic modulus and fatigue endurance limit assumptions. Researchers will evaluate the performance of IDOT’s extended life pavement design projects over the past 20+ years as well as examine the impact of climate change, truck platoons and increased axle loads. Updated pavement designs have the potential to result in cost savings and improved long-term pavement performance.
