Composite Pavement Systems

Greetings!
Many transportation agencies have expressed interest in composite pavement systems, specifically a) high-quality relatively thin hot-mixed asphalt (HMA) surfacing over a new portland cement concrete (PCC) structural layer and b) high-quality relatively thin PCC surfacing atop a thicker, structural PCC layer. SHRP 2 Project R21 (Composite Pavement Systems) reviewed the behavior, material properties, and performance of these two types of pavements.
The final report describes the evaluation, improvement, and validation of applicable structural, climatic, material, and performance prediction models, and design algorithms. It also includes recommendations for construction specifications and techniques, life-cycle costing, and training materials. Volume 1 focuses on HMA/PCC Pavements; Volume 2 focuses on PCC/PCC Pavements; and the appendices provide survey results, details about the evaluations, and the history of the pavements.
SHRP 2 Report S2-R21-RW-1: 2008 Survey of European Composite Pavements explores in-service composite pavement sites in the Netherlands, Germany, and Austria in order to help assess the design, construction, and performance of composite pavement systems. The report also examines other issues that should be considered in the design and construction of new composite pavement systems.
