There's nothing but clay soil around here. With all the construction around here, it gets on the asphalt roads all the time. After a good rainfall, there's no signs of the clay.
Most likely, the clay is stuck to the asphalt and didn't actually etch it. It should wear off shortly.
Don't try muriatic acid as it will just damage it and leave spots where you use it.
A light pressure washing or steam cleaning may work but you'll want to do the entire walkway or you'll be able to see where it was cleaned and where it wasn't
