Caltrans Mechanistic-Empirical (ME) Design - Phase 2 Implementation

Mechanistic-empirical (ME) pavement design will foster better pavement performance using traditional and innovation materials and designs, lead to better performance prediction (to support the Caltrans PMS, life cycle costs, and budgets), and improve cost-efficiency by producing less costly designs. This research will help Caltrans implement ME applications as mandated in the Caltrans Issue Memo from 2005 that adopted implementing ME along with workplan and schedule. Full implementation is expected to take 5 years. This project includes: produce a simplified tool for flexible pavement design based on ME; update catalog for concrete pavement design; update field calibration and comparison of ME applications; show how current practice results differ from ME for new and rehabilitation design; and produce a library of ME inputs for typical Caltrans materials.
