After the initial pass, what should be done with the joint on remaining passes?

Explanation:
After the initial pass, the joint should be compacted on the remaining passes. The goal of these passes is to densify the asphalt mat and the joint while the material is still hot, which helps close air voids, create a solid bond between the old and new lifts, and produce a uniform, smooth surface. If compaction isn’t continued at the joint, the area can remain weaker, with higher permeability and a greater risk of cracking or settling. Edge sealing and surface cooling aren’t the primary actions during these passes, and keeping the material hot and well compacted is what yields a durable joint.
