LONGITUDINAL JOINTS: PROBLEMS AND SOLUTIONS

Construction of durable longitudinal joints is a critical element in the longevity of Hot Mix Asphalt (HMA) pavements. Achieving uniform density both longitudinally and transversely on the pavement will assist in meeting the goal of high-performance HMA pavements. A variety of techniques have been successfully used to construct good longitudinal joints. The objective of this document is to identify proper techniques for the various procedures, not to recommend a single technique.
