METHODS
This study consisted of four steps: the first step consisted of a literature review of
composite pavement systems in the U.S. and worldwide, the second step included a survey of
state pavement design engineers from state DOT’s, the third step used mechanistic-empirical
pavement distress models to study the response of composite pavement systems, and the final
step investigated the feasibility of composite pavement systems by a life cycle cost analysis.
Literature Review
The literature review portion of this study was performed using available electronic
databases including: Transportation Research Information Services (TRIS) bibliographic
database, the catalog of Transportation Libraries (TLCat), the Catalog of Worldwide Libraries
(WorldCat), the Transportation Research Board Research in Progress (RiP) and Research Needs
