    Year after year, the number of heavy trucks on Bangladesh's highways increases. Heavy loads are one of the most typical causes of pavement distress. The distribution of contact stresses between tires and the pavement surface has a big impact on how pavement distresses start and spread. Hence, to accurately and exactly describe pavement responses, the distribution of contact stresses ought to be 1st investigated thoroughly. Pavement is a complicated structure made up of numerous layers of various materials that determine how it behaves under stress. Finite Element Modelling (FEM) is becoming a more prominent tool for researchers to solve complex structural mechanics problems in engineering. There is currently a shift toward more mechanistic design methodologies in pavement analysis to reduce the limits in calculating stress, strain, and displacement. We used ABAQUS software to perform flexible pavement finite element analysis in our study. This research aims to learn more about the stress-strain characteristics of asphalt pavement by examining a variety of traffic and loading parameters, as well as their relationships with pavement distress and failure initiation. For validation, we compared our ABAQUS results to IITPAVE.
