Review of Illinois Multiple Stress Creep and Recovery Data for Future Implementation

The multiple stress creep recovery (MSCR) test, per AASHTO M 332, or as a supplement to M 320, has been widely implemented across the United States and in other parts of the world for assessing the rutting resistance of asphalt binder. Meanwhile, the Illinois Department of Transportation (IDOT) has conducted wide-ranging MSCR testing since 2006 but has not yet implemented this test into the binder specification, which utilizes AASHTO M 320 with other PG Plus tests for modified asphalt binder. This report presents a review of the existing literature and an update of specifications in the United States for the rutting resistance of asphalt binder. The report also presents an analysis of existing MSCR data collected by IDOT and a machine learning model with the ability to predict asphalt binder elastic recovery using MSCR. This model demonstrated the potential effectiveness of MSCR to serve as an appropriate surrogate for this test, but further study is needed of Illinois mixture performance compared to MSCR to best understand how this specification can be implemented for local materials and traffic levels.
