Just bought a house and the driveway has some cracks and when the delivery trucks came they damaged the driveway (gouges and when it was hot one day the tire indented the asphalt). The repair guy said the asphalt is tennis court grade, not commercial grade, which is why it is so soft. He suggested that rather than patching the 6 places, he could lay down 1 1/2" of commercial grade asphalt on top. He said the asphalt bonds permanently to the bottom layer and is good for 30 years (although the warranty is only for 2 years). Any ideas re whether this process really does hold up for that long? It makes sense to me to go this route rather than having numerous patches that will be visible. I am worried about ice getting between the layers and lifting it up. Anyone out there with experience with this?

A neighbor next to my parents house had theirs done this summer and it looks great. I don't know what the warranty is.

I can't see ice being a problem. They do this re-surfacing on highways throughout the country in all temps.
That is a question for the installer. Ask if ice heaving is part of the 2 year warranty.

Also ask the installer at what time can sealer be put on the new surface. This will help protect the new surface also and help get your 30 years.

What ever the delivery company wants to pay for to repair the damage their trucks did would be OK,

The re-surface does great but a patch with a seal coat is great also.

But all of our highways and streets are resurfaced all the tiime, this is a common method.
