Asphalt driveway garage seam

A gap of approx. 3/8" has appeared between our asphalt driveway and garage. I'm looking for a product to fill the gap. Several products (primarily caulks) seem to do the job, but none actually say so. I assume there must be products commonly used because most asphalt driveways abut masonry at some point. Any suggestions?

Before you use the sealer as reference above. use a backer rod. You condition is very common. Due to asphalt absorbing heat and releasing heat during cold make it very flexible and separation from garage concrete is common. Most likely the gap is also at least a half inch deep. Using a backer rod will hold the leveler in place for many years.

Thanks for the information. My plan is to fill the space with sand now to stabilize it until spring then remove the sand and make a long-term repair as suggested.

The sealant is the long term repair, you can use the backer rod, I just use sand, fill to within 1/2" and pour it in, cures overnight even in cooler weather!

In the past I use to use sand. But over time it filters down and dissipates. The backer rod provides a base for the sand or sealant to lay on. I use to "repair" that condition very year. Since using backer rod I haven't touched in the past 5 years.

Guys, I suspect the problem was caused by settling. My understanding is the self-leveling sealant will last a long time with sand, longer with the backer rod. Given that the backer rod is inexpensive and (appears to be) simple to insert, that's probably the way I'll go.
