Evaluation of Pavement Distresses and Rehabilitation Strategies for Rigid Pavements

Abstract: Rigid pavements are an essential component of transportation infrastructure, providing durability and long-term performance under varying traffic and environmental conditions. This paper evaluates the performance of rigid pavements using different assessment techniques, including non-destructive testing, structural analysis, and material evaluations. Recent advancements and maintenance strategies are also discussed to enhance pavement longevity.It effectively highlights the significance of rigid pavements in transportation infrastructure and emphasizes the need for performance evaluation. The methodology section outlines different assessment techniques, such as non-destructive testing (FWD, GPR), distress surveys, and laboratory material analysis, ensuring a comprehensive evaluation approach.the results indicate that deflection values were within acceptable limits, material strength met standard criteria, and preventive maintenance significantly reduced pavement distress progression. The study further suggests that timely maintenance strategies like joint sealing and slab replacement improve pavement longevity. The conclusion emphasizes the integration of advanced monitoring techniques, such as smart sensors and real-time data analysis, for improved pavement management. Overall, the abstract effectively summarizes the research scope, methodology, findings, and recommendations, making it a well-structured and informative overview of the study.
