The input parameters used, evaluation criteria, and the results are summarized below, in table 1. Austroads pavement design guide 2003 two design processes for flexible pavements empirical design chart •.
Design Chart For Flexible Pavements Based On Using Mean Values For Each Input. Flexible pavement designs based on aashto 1993 guide Pavement thickness, this section provides comparison tables showing the various rigid and flexible pavement thicknesses calculated according to the aashto pavement design methodology.

Wearing layers are typically 2 to 4 inches (50.8 to 101.6 mm) thick, subbases and bases range from 4 to 10 inches (101.6 to 254.0 mm) thick. The determination of alternate designs and the selection of an optimum design based on costs, conservation of materials, etc., will also be discussed. This value can be estimated based on: Must use design chart for flexible pavements based on using mean values for each input chart.
