Building small fence over asphalt?

I just bought a house with a yard that is almost entirely fenced in, but open to the driveway. I’d like to build a small privacy fence over a portion of my driveway to fully enclose the backyard space for my dog.

Ideally I wouldn’t have to build this over asphalt, but due to the stair placement (purple in my diagram) I think I have to. The total fence length is ~10 ft, and I’d like one of the (presumably two?) segments to be a gate. The problems I’m having are that I need to anchor this into my asphalt driveway, as there’s my house on one side and a chain link fence on the other side of the driveway.

What is the best way to do this? From what I can tell, I should be able to impact driver in some bolts to fasten down posts, and then I should be able to construct as normal, but I was wondering if there’s a better way to do it, or anything specific to buy/avoid, since I can’t find too much about doing this with a driveway.

    Likely the asphalt is too thin for much support. You should go down 2 feet and concrete the post in.

    The frost line can vary by a lot depending on your location, so just check what local code is.
    I’m thinking you’d would want to create a hole in the asphalt just slightly larger than the post, dig down and then concrete the post in. Once this is set you can just patch around the post to seal it. As was mentioned, the asphalt is likely going to not be thick enough to anchor to. In my opinion better to do a little more work now to save headaches in the future.
    Dont forget to call 811 before digging. Its not worth the potential injury or cost to hit a buried utility.
