AASHTO DARWin Task Force Development of DARWin-ME

R21. Composite Pavement Systems
Advertised on March 2007 – under contract negotiations
• Objectives:
– Develop performance models and design procedures for longlasting,
easily maintained new composite pavements
– Investigate the behavior and critical performance parameters of
composite pavements.
– Develop material requirements for all layers of the composite
pavement, including the subgrade.
– Recommend construction and quality control procedures
– Develop a long-term evaluation program to provide for future
refinements of the design procedures and models.
• Budget: $4,000,000
• Duration: 4 years
