Abstract:The construction of longitudinal joints to specified densities significantly impacts the performance and service life of asphalt pavements. Ensuring proper compaction is essential to creating impermeable joints that can withstand water infiltration, prevent moisture damage, and enhance long-term performance. Various entities, including state departments of transportation, industry organizations, and research institutions, have conducted extensive studies and developed guidelines to enhance the performance of longitudinal joints. The objective of this study was to comprehensively review existing literature on the current best practices for longitudinal joint construction. To achieve the aim of the study, the research team gathered and critically reviewed available literature regarding the best practices for longitudinal joint construction and the utilization of different techniques and materials to improve longitudinal joint density.
