It is now possible to regularly apply an analytical-empirical (or mechanistic) method of structural pavement evaluation because to the rapid development of technology and software over the past ten years. It is described how to determine the modulus of each structural layer in a pavement system. These moduli are determined non-destructively and in situ under conditions very similar to those caused by heavy traffic. The method is analyzed using empirical evidence, and some practical examples are given to illustrate its use. An analytical-empirical approach is recommended for the structural design of pavement systems. An "analytical method" or a "mechanistic method," as it has an important empirical component, is often referred to as such, and therefore the term "Analysisal-Empirical" is more appropriate. FWD test has been conducted at the designated sites, with KGP Back software being used to analyze the results (IRC 115-2014), and IIT-Pave software verifying the design.
