Filling the gap between driveway and garage

There is a long(garage wide) gap running in between the driveway and the garage, in the size about 1/2"-3/4" wide(please refer to the attached pictures for the gap), and about 2"-4" deep.
I think the rubberized Asphalt Driveway Crack filter(like this: https://www.homedepot.com/p/Latex-it...2376/100001983) normally take care of only <1/2" crack and not for deep one.
Could you please advise the right filler/patch for my case?
Since the gap is a bit deep: 2"-4", should I fill it with top soil first I apply any filler?
Thank you!

If I was doing it, I would probably buy a bag of clean silica sand and a quart tube of Loctite S20. Pour the sand in until its about 1/2" - 3/4" from being full. Then fill the rest with the self leveling sealant. You would need to make end dams out of sand since it will just flow out the end like a river. I kind of like to sprinkle sand over the top when I'm done... but thats up to you.

Alternatively you can use foam backer rod, stuffed down into the joint but IMO just using silica sand works well.

Thanks for the suggestion!
I just checked my local HomeDepot, they don't have Silica Sand in stock, but they have Play Sand and Paver Sand. Can I use one of them instead? What's the difference between them?
About the Loctite S20 you mentioned, it looks to me it's used for concrete, with grey color. But in my case, the concrete floor of the garage looks good, but the asphalt driveway moved and caused the gap, so should I use the black color asphalt filler instead?

Any clean sand will work. Use whatever crack filler you like.

Silica and play sand are very fine grain, for what your doing any of the three will work!

The self leveling sealer mentioned is gray, they make it in black which may look better but the BBS typ dont carry so you have to do a little searching to find.

For 50 years I have struggled with gaps and cracks on asphalt 1600 square foot driveway lined with 200 feet of Belgium blocks.

Found the modern high technology solution in strong, resilient Sikaflex Self- Leveling Sealant.

Traditional gap fillers harden, then gaps develop from freezing and thawing. Sika does not leave cracks in cold weather, it adheres to sides of gap then expands and contracts,

Unlike typical caulking, it flows into cracks. If the is deep 1/4” crack it will flow in and dry. A second fill may be needed, but the deep crack is filled, not just superficiality. Use small paint brush to smooth out ridges.
