Analytical Pavement Design Based on Method of Equivalent Thickness: Approach to Transform from Catalogue Based System to Easy to Use Analytical System

Most empirical catalogue based methods do not readily accommodate the available materials properties and environment in to the design system. Dependency on factual physical changes within the pavement layers due to traffic loads and incorporating individual materials properties are key features of the analytical pavement design process. Using mechanistic-empirical (M-E) method based on Method of Equivalent thickness (MET),pavement design charts which are very easy to use,ensuring the desired pavement life in engineered way has been developed. By using this method an approach has been made to transform from catalogue based system to easy to use analytical system. As the existence of a system is depends on its sustainability, the study examined the sustainability in terms of engineering, economic and manoeuvring the proposed method. To examine the reliability of the proposed method a full scale experiment has to be performed. Provision of incorporating local available materials properties in to the design process, easy to use design charts, reasonable cost efficiency, accommodation of drainage characteristics and acceptance makes the proposed analytical design method sustainable.
