We have an asphalt driveway that includes a paved RV parking area. Over the years the asphalt started to sink down where the RV wheels sat. The RV always had to be parked in the same spot, within 6" due to the slideout clearance and access along the other side. Eventually the "dip" in the asphalt got to be over an inch deep.
Last summer I cut out the asphalt with a power saw, and poured two concrete strips for the RV to sit on. I used extra rebar, and extra cement in the mix.
We have cold winters and the freezing and thawing with the weight of the RV in the same spot month after month made asphalt a poor choice.
