Adjustments at the joints should be made before the compaction process to ensure proper bonding and density of the asphalt layers. Making adjustments prior to compaction allows for better alignment and integration of the asphalt at the joints, which is crucial for preventing future issues such as cracking or moisture infiltration. During this stage, the material is still workable, allowing for effective manipulation and adjustment to achieve the desired results. This proactive approach ensures that the joints are secure and effectively integrated into the surrounding pavement structure, enhancing the overall quality and durability of the finished surface.

Making adjustments after the asphalt has cooled or once the paving is finished would not allow effective modifications, as the material would be too rigid to manipulate, which could lead to compromised joint quality. Similarly, addressing joint adjustments at the beginning of the project does not align with the necessary timing that coincides with actual paving activities where the situation and material condition can be effectively evaluated.
