Abstract: Interlocking concrete paver blocks (ICPBs) are increasingly adopted in urban transport infrastructure due to their modularity, structural adequacy, and ease of maintenance. Bus stops and parking areas are subjected to high contact stresses, repeated braking and acceleration forces, and frequent static loading, which often lead to premature distress in conventional bituminous and cement concrete pavements. This study examines the suitability of ICPBs by evaluating their mechanical strength, rutting resistance, and maintenance performance under realistic service conditions. The investigation focuses on compressive strength, flexural behavior, load distribution through interlock and bedding layers, and resistance to permanent deformation caused by repeated wheel loads. Particular attention is given to the role of block shape, thickness, jointing sand, and laying pattern in enhancing structural performance. Field and laboratory evidence from previous studies indicates that properly designed ICPB systems can achieve high load-spreading efficiency, reducing subgrade stress and surface deformation even under heavy vehicular traffic. Rutting behavior is assessed through comparisons with conventional pavements, highlighting the importance of adequate edge restraint and base preparation. Maintenance aspects, including ease of replacement, lifecycle cost, and service disruption, are also reviewed, demonstrating clear advantages in urban settings where rapid repair is critical. The research further discusses environmental and operational benefits, such as permeability, reduced urban heat effects, and adaptability to utility interventions. By synthesizing available experimental findings and performance observations, this paper aims to provide a comprehensive evaluation framework for the application of interlocking concrete paver blocks at bus stops and parking facilities. The findings support the hypothesis that ICPBs, when designed and constructed according to established guidelines, offer a durable, rut-resistant, and maintenance-efficient alternative to conventional pavement systems in heavily loaded urban traffic zones.
