Abstract
Pavement design is an integral part of sustainable and resilient infrastructure. In Kerala, flexible pavements undergo premature failure before their design life. There are many reasons for this, including inappropriate material selection and lack of dependable traffic and axle load data. The study analyzes the performance of permeable flexible pavement using IITPAVE software, which evaluates stresses, strains, and deflections in a linear elastic layered pavement system under applied loads. The research follows the mechanistic-empirical method, utilizing key input parameters such as layer thickness, Poissons ratio, elastic modulus, wheel load, and tire pressure. The study compares critical pavement strains computed using IITPAVE with allowable strain values from IRC:37-2018 guidelines. Results indicate that the actual horizontal tensile strain at the asphalt layer bottom and the vertical compressive strain at the subgrade top are well within permissible limits, ensuring the pavement's structural safety. The findings confirm that the design thickness of 595 mm is sufficient for anticipated traffic loads, demonstrating IITPAVE's effectiveness in pavement analysis.
