Longitudinal Joint Sealant

Longitudinal joint sealant is a hot applied asphalt joint sealant used to extend the life of the longitudinal HMA joints. It is applied in widths 12” or 18” along the longitudinal joint of every layer of HMA. It is flow resistant and non-tracking within 15-30 min.

 

By migrating 50-75% into the HMA void structure, LJS reduces water and air intrusion into the longitudinal joint. LJS helps extend the life of the HMA and allows for better compaction rates on the unconfined edge.
