In terms of how the sleepers will be bedded and fixed into the concrete though, am I looking good? Or are the steel dowels unnecessary?
I’m laying them straight onto level compacted hardcore and sand blinding. But then yours sounds like it’s retaining more and next to a public highway, mines just my lawn.
I don’t think decking screwed to the sleepers will help with slippiness and also in my opinion looks rubbish. Possibly composite decking may be better?
