The transportation system of a country plays a vital role in supporting the overall growth of the nation. These transportation systems are a set of complex networks of different types of assets which continuously undergo deterioration at an uncertain rate. The Federal Highway Administration (FHWA) has been considerably proactive and robust in responding to the need of the times. State Departments of Transportation are asked to create regulatory TAMP (Transportation Asset Management Plan). The purpose of the TAMP report is to develop a systematic framework of the Transportation Management System to coordinate and manage the assets throughout the foreseeable future with the help of various tools considering the historical and predicted data by the state agencies. Each state is required to develop a risk-based asset management plan for the National Highway System (NHS) to improve or preserve the condition of the assets and the performance of the system. This research work is based on a comparative analysis of the TAMP reports developed by the U.S. states - Florida, Tennessee, North Carolina, Pennsylvania, Utah, Illinois, Virginia and California. This analysis is aimed at establishing a thorough collection and comparison of the data acquired from the TAMP reports. The analysis is done on the basis of the criteria sheet which was developed based on the different components of a TAMP. Also, the current deterioration models used by the mentioned states will be compared with several other models in order to analyse the efficiency of the models. The effect of various impacting parameters contributing to the deterioration of pavements is also analyzed in the form of a few IRI models. The results of the study will be helpful in building a link within the state agencies and collaborating towards the transportation system development mission.
