Excessive raking of the longitudinal joint will result in what?

Excessive raking of the longitudinal joint reduces the amount of asphalt left at the seam, so when compaction happens there isn’t enough material to achieve proper density at the joint. That inadequate density creates voids and a weaker bond between the two lanes, making the joint susceptible to moisture intrusion, raveling, and early distress. The key idea is that removing too much material from the joint directly leads to low density there, not uniform density or changes in cross slope.
