Whether you should resurface or replace your asphalt driveway heavily depends on its condition. If the foundation is solid and the damage is minor, resurfacing is your best bet because it’s more affordable and faster than replacing the driveway. But if your driveway has foundational problems and/or severe damage, like large, deep cracks and potholes, then it makes more sense to replace it. 

You should contact your driveway installer before winterizing a newly installed driveway. Winterizing it before the asphalt or concrete has fully cured can damage the driveway. But in many cases, you don't need to winterize a newly installed driveway anyway since it's likely freshly sealed and won't have much damage yet. 

Yes, it’s possible to seal your driveway too much. Whether you have an asphalt or concrete driveway, sealing it every year opens your driveway to potential damage. Sealing an asphalt driveway annually may cause the seal to crack and peel even more. It may even trap oils within the asphalt that can leave you driving on a soft driveway. Avoid sealing your concrete driveway too much to prevent the concrete from cracking. If water enters these cracks, it can freeze, expand, and cause the cracks to worsen.

The three most common types of asphalt are hot asphalt, MC cold mix, and UPM asphalt. Hot asphalt is used most often for paving and patching roadways while it’s hot and workable. MC cold mix asphalt cures more slowly than hot asphalt, but it can be used for temporary patches and repairs in low-traffic areas. UPM is also used cold, but it can be used as a longer-term fix, usable in almost any conditions at almost any temperature.
