If I lived in a warmer climate (and soon it may be) I would replace my driveway in a heartbeat. I wonder if there's any material I can use that will:

• stand up to freeze and thaw cycles

• tolerate occasional snowblower use

• be less than 100% impervious

• be usable on a 20-degree slope

I'm thinking even if there's something that could handle the first 3, the last one would be a deal-breaker. My driveway is 150 feet long. Half of it is asphalt and half concrete. The 20 feet or so at the end slope down to the street. Your thoughts?
