What would be a cheap and interesting layer of something to paint over this
driveway of red tiles that is disintegrating due to water seeping into the
tiles and splitting them open when it freezes?

I suppose an ordinary cement type mixture would be cheapest, but to our
minds would not look that good. If I used cement what would be the minimum
thickness i could use and still park vehicles on it?

The drive is very solid and I dont want to be digging anything up. I have
seen some kind of 'ground-up' rubber (probably ground-up car tyres) in
childrens playground around the swings etc. Would that be easy to put down
or stand up to cars driving over it, or be waterproof enough? Also there are
some resin finishes but I guess they would be difficult to put down and
probably expensive?

Grateful for any suggestions. Thanks.
