Proven models and design procedures to confidently design long-life, low-cost composite pavement systems.
Composite Pavement Systems (R21)
Pavements that combine layers of asphalt and concrete generally have a long service life with excellent surface characteristics, structural capacity, and the ability to be rapidly renewed. However, the majority of roads containing these composite pavements resulted from maintenance and rehabilitation activities. Few roads are intentionally designed to utilize composite pavements because reliable guidance for designing and using these materials has been lacking. U.S. Transportation agencies require guidance, specifications, objective and reliable performance data, and life-cycle cost analyses to support use of these pavement systems.
SHRP2’s Composite Pavements Solution provides detailed performance data on existing composite pavement systems, and provides step-by-step guidance on designing and constructing two types of composite pavements (Hot-Mix Asphalt and Portland Cement Concrete) using procedures consistent with the Mechanistic-Empirical Pavement Design Guide (MEPDG). The guidelines will enable agencies to design composite pavement systems with confidence to produce long-lasting roads with lower life cycle costs.
