Asphalt patch to make a ridge ?

I'm going to do the same thing for a sidewalk. My plan involves Sackrete and a lot of cursing. To answer your question, though, for sure, concrete won't flatten!

But would one put sackrete over exhisting black top, sounds hideious.

1. My walkway is concrete.
2. It won't flatten or stick to your shoes in hot weather (I'm in Houston - same latitude as Cairo).
3. If someone climbs it with a heavily-laden trolly, it won't go squish.
4. If the bare concrete ends up looking hideous, you can always paint your handiwork in vivid colors, maybe with some butterflies or pastoral scenes. For the more marital, you could apply decals depicting great naval battles or events taken from history, such as the coronation of Charlemane or Neal Armstrong's walk on the moon. You could even, while the concrete is wet, poke a couple of holes in the top and thereafter, each day, adorn the creation with fresh-cut flowers. For my part, I have a plan to make the hump attractive. I haven't worked out all the details, but the plan involves Legos and a small jar of Mayonnaise.

Sorry I must have misunderstood your reply to my question of whether or not Tamp & Set Stone Asphalt Patch would flatten out.

Sounds pretty cool, good luck.
