I have a seam between a blacktop driveway and a concrete wall where all of the caulking material is coming loose.
The concrete/asphalt gap is like 1/2" and the seam is 8 feet long. Behind the seam there is a fairly large space in the dirt, consider a cylinder 3/4" in diameter the length of the seam.
Any ideas what I should caulk or seal this gap with?
Thanks.

Quikrete asphalt mix, at any big box store.

Fill the seam with pea gravel to about 1/4" from top. Then fill the top 1/4" with asphalt sealer such as this
Pack the gravel down before covering with sealer.
Check latexite.com. They have a product that is like 3/8 or 1/2 rope that goes in the gap. Then you heat it with a torch and it melts forming a tough but flexible filler. If you don't use that, then I'd fill it as suggested above, and then use the liquid crack filler available at home centers. Probably should use two steps, filling it part way, let it cure, then fill it the rest of the way.
Thanks. Several good ideas. I may use the latexite stuff for some driveway cracks
Anyway, I have decided to go with the "pea gravel + asphalt sealer" approach. That leaves me with one question.
Should I use the stuff in caulking tubes labeled "DAP Blacktop Asphalt VOC sealant" OR should I use the more liquidy "Asphalt Crack Seal" in the quart sized squeeze bottle?
