Concrete Driveway Large Crack Repair

After watching about 20 videos and instructions on how to repair driveway cracks, I've decided on the following instruction: https://www.todayshomeowner.com/vide...s-in-concrete/ In this video, he used Quikrete® Concrete Resurfacer to patch the cracks, and then resurfaced the driveway.

Lowe's had two types of these concrete resurfacers:

https://www.lowesforpros.com/pd/QUIK...Sealer/3013802

I went ahead and bought the self-leveling one.

I've attached the photos of my driveway. The cracks are as wide as 3/4" and seems to be deep as 8 inches, which is filled with dirt over years. Do I need to remove all the dirt inside or just down to 1/2" to an inch?

There is nothing that is going to permanently repair a cracked cement slab.

It cracked to stress caused by motion which is still present and any repairs will be short lived and the crack will reappear.

Best bet is to fill with sand to about 1/2" and fill with self leveling sealant which will have some give,
