Synthesis of design and construction practices

This section discusses the results of the state-of-the-practice survey and the technical and 

design methodologies for composite pavement systems and modeling of typical distresses 

affecting composite pavement systems.  This modeling helped understand how the distresses 

affected different composite structures as compared to traditional flexible pavements and among 

themselves.  The economic analysis consisted of a LCCA to investigate the cost implications at 

both the initial construction stage and throughout the pavement service life.  Four pavement 

structures were considered: traditional flexible, traditional rigid, composite with CTB, and 

composite with CRCP base.
