I live in the Northeast, and we have lots of hard winters. My driveway had many cracks with most under ¼ inch in width, but a few larger. So last summer, I cleaned those cracks with jets of water, let them dry and filled them in with patch fillers. Some I got from Home Depot (Latex-ite 1 Gal. 2X Premium Blacktop Crack Filler). I also got a little bucket of trowel patch filler from Walmart for the bigger cracks. Anyway, I applied all these per their instructions early last summer. A couple weeks after that I then sealed my driveway with a product from Home Depot: (4.75-Gal. Ultra Shield Driveway Filler Sealer), again per the product's instructions, and with two coats.
A harsh northeast winter later, I have been dismayed to see most of my cracks are back to their state where they were before I patched anything. A few repairs that were done in the shade seemed to fair better. Yea we had 75” of snow or so that I only used a shovel to clean up with, no salt etc.
Anyway, do you have any recommendations for how I can do this right?
Update, here are some pictures:
