摘要：	The longitudinal joints between asphalt mats often deteriorate faster than other areas. The primary reason is believed to be the lower density achieved at the joints. A uniform density gradient is desirable through out the asphalt pavement mat. However, because of the difficulty in compacting the unconfined edges, lower density zones occur at the joints. The density gradient arises from the low density at the unconfined edge when the first lane is paved, and relatively high density at the confined edge when the adjacent lane is paved. The objective of this research project was to conduct a literature review on longitudinal joint construction for hot-mix asphalt pavements. The review covered the issues related to the principles of hot-mix asphalt paving and compaction for longitudinal joint construction, longitudinal joint problems, and some longitudinal joint construction techniques and specifications from different studies. Specific recommendations have also been made for application in the State of Kansas. / NOTE: Final rept. Aug 98-Mar 03. / Supplementary Notes: Sponsored by Kansas Dept. of Transportation, Topeka.
