The conditions of road pavement affect economy, safety and comfort, traffic and travel times, emission levels, and vehicles' operating costs. The research paper focuses on one of the most important factors that lead to road deterioration and the failure of maintenance operations, which is the incorrect identification of the causes of distresses and their negative impact on the economy, safety, and the environment. To identify these causes and effects, the researcher used an integrated methodology that included reviewing and analyzing previous studies, preparing a questionnaire filled out by experts, and analyzing historical data for a case study (AL-Kut-Maysan Road). The results show that the reasons for the inaccurate identification of the causes of distresses are seven factors, the most important of which is the adoption of old and fixed work methods for all cases of deterioration, as well as the lack of training and tools used in some maintenance departments. The results of the case study analysis also show the negative effects, including economic losses, an increase in the number of accidents and emissions, as well as the road being out of service due to the failure of the maintenance process.
