Knowledge gained from the parametric analysis of different sections using AASHTO 1993 and MEPDG is expected to be useful to pavement designers and others in implementation of the new MEPDG for future pavement design. Cost comparisons of sections stabilized with different percentage and type of additives showed that CKD-stabilization provides economically low cost sections as compared to lime- and CFA-stabilized sections.

It is found that the design thickness is influenced by the type of soil, additive, selection of material property and design method.

Specifically, comparisons were made for a range of different sections consisting of cementitious layers stabilized with different types and percentages of additives. The primary objective of the study presented in this paper is to develop design curves for performance prediction of stabilized layers and to compare semi-rigid flexible pavement designs between the empirical AASHTO 1993 and the mechanistic-empirical pavement design methodologies. The AASHTO 1993 design procedure is based on empirical equations derived from the AASHO Road Test conducted in the late 1950s in a test track in Ottawa.
