SPR-5033: Optimizing field compaction of granular materials: Research and guideline development

This proposal addresses INDOT’s need for material-specific, performance-based compaction guidelines by evaluating alternative lab and field-testing methods. The research will identify optimal compaction procedures and field control strategies tailored to each material, helping INDOT reduce variability, improve long-term pavement performance, and implement more cost-effective, durable, and consistent construction practices.
