| Technical Analysis
To understand the technical advantages of composite pavements, a technical evaluation
was performed. This evaluation involved mechanistic modeling of a typical composite pavement
structure that was obtained using the most promising methodologies available for the design of
composite systems.
Designed Composite Pavement Structures
To compare the output (primarily thicknesses) and layer recommendations from the
different design methodologies, it was important to design composite pavement systems for a
fixed set of conditions (inputs). Therefore, the various design procedures were followed to
design composite pavement structures for the same input parameters (e.g., traffic, design life).
Table 6 shows the basic design inputs and Table 7 the typical values used for the material
properties of each layer used for the structures. (NCHRP, 2004; Huang, 2004).
