Ashphalt driveway: how difficult is it to cover the old one?

Lets see... if it's really bad, you need a bobcat or front end loader of some sort and a dump truck to remove the old drive. Then you need to remove the previous base, load that in the dump truck, and haul it to an asphalt recycling center.

Then you need a paving machine, a steam roller, a hand tamper, a couple of laborers, and a dump truck full of asphalt.

Somehow I think it might be cheaper to hire someone.

Re-sealed or torn out and re-built? If you mean simply re-sealed then all you need is a sunny afternoon and a large push broom to spread asphalt sealer that looks similar to tar. Available at your local home center.

If you mean torn out and re-built, you'd be much better off replacing it with a driveway made of concrete pavers. Easy enough to do yourself.

i covered with blue plastic tarp first from harbor frate.

Huh? That would be maybe 5x the price at DIY, and hardly could be considered "easy".
