Blacktop/Concrete seam - How to seal or caulk?:


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?

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.
