Abstract: The country's road network has been overloaded and is experiencing early breakdown due to the dramatic growth in vehicle population and higher axle loading pattern over the past decade. Before developing an acceptable overlay type and design, it is important to determine if the pavement has a functional or structural defect based on the type of degradation existing. Conditions that compromise the pavement's load-bearing capacity lead to structural breakdown. Structural deficiencies result from insufficient thickness, cracking, deformation, or disintegration. When the pavement is not smooth and comfortable to ride on, a functional deficit occurs. Causes such as excessive surface deformation (potholes, corrugation, faulting, blow up, settlement, heaves, etc.), hydroplaning, splash from wheel paths, rutting, and poor surface friction and roughness can lead to this. Vehicle Operating Costs (VOC) and the amount of service a facility can provide its customers at any one moment are both affected by its functional state, which in turn affects the economy of the country. The remaining service life (RSL) of a pavement structure can be estimated by predicting its deterioration over time. This allows for the evaluation of different rehabilitation strategies and alternative designs, as well as the allocation of long-term funds for pavement preservation. Furthermore, they are able to foretell how the portions will respond to therapy. Primary response, structural performance, functional performance, and damage models are the four main categories into which the infrastructure prediction models fall. The elements that contribute to road degradation are multi-faceted and regional in character. A definitive plan for the rehabilitation of roads cannot be reached without first conducting an extensive investigation of the degradation process under different soil conditions and climate zones. The current study is an attempt to fill the gap in the literature by including all state road types, traffic situations, and soil types in a comprehensive analysis.
