Optimizing Aggregate Foundation to Improve Concrete Pavement Performance

Status:  Complete
Report Date:  08/12/2015


This project evaluated how aggregate base properties affect concrete pavement performance in an effort to optimize those properties. A 1.4 gravel-to-sand ratio for aggregate bases produced the best combination of drainability and stability. Open graded aggregate bases reduced subsurface moisture relative to dense graded bases, but produced similar structural stability.
