Hi. I do pavement management for a living. Civil engineer by education and now I do it across the US. This looks to be northwest Florida and the pavement section appears to have been subjected to flowing water. In that part of Florida, sand and seashells are often a mixture (a very poor one) for the subbase. The asphalt course is laid after a thin coat of asphaltic oil (RC-250?) is sprayed on the surface. In this case, the asphaltic oil didn’t bind well to the subbase and this is what you get when the water flowed over and around it and hydraulically separated it from the subbase.
Edit: typo and thanks for the gold and other awards!

Hopefully there’ll be another storm coming in the opposite direction and can move it back 👍
