You are essentially asking people to determine if the material under your driveway is suitable for pavers without telling them what is under the driveway.

I think he means he wants to pull up the top layer of asphalt and lay pavers over the second layer. It should work, but I think a key question here is slope and surroundings, because you have to contain that sand layer, and also climate. But also, I think a similar question has been asked here before. Maybe search the forum for "asphalt" or that plus "pavers" and see what you can find.
