Best options for driveway?

[Civs]

Hi

Just looking for some advice on extending my existing driveway. My current driveway consists of a sloping 150mm concrete driveway with a rather drab tamped finish.
I wish extend my drive by creating a spur at 90 degrees to the orignal drive that will provide a flat area where I can work on my weekend car.
I had intended to create a new 100-150mm reinforced concrete slab on an aggregate sub-base and then have it and the existing drive covered in a resin bonded aggretgate.

My question firstly is, is this the best way of doing it or would just a good agg. sub-base with a tarmac base and the bonded aggregate as a wearing course be sufficient?

Secondly will the resign bonded aggregate provide a good working surface, as I've had the problem in the past on tarmac drives where when jacking the car the wearing course has been scratched/marked, by the jack wheels pushing into the surface, and it has ended up looking messy.

Any help much appreciated.

I'd suggest that a concrete slab would be a better extension option than a bitmac bay, mainly because, for small areas, it's cheaper to use concrete than a bitmac or asphalt. However, in light of what you've revealed to be the function of this extension area, a concrete slab is better able to resist point deformation (as caused by a trolley jack) than would be a bitmac area.

Regarding the suitability of a resin-bonded surface as a working surface, I think you could expect to lose some of the surface coating regardless of whether a concrete or bitmac substrate is used. I would strongly recommend you use decking sheets over the surface before you carry out any workshop tasks, especially those involving trolley jacks.

Tony's right; protect the surface against high point loading or impact with sheets. But otherwise Ronadeck Fast Grip is ideal for your needs and interest.

And smooth out the tamps either by planing the concrete to make it flat, or lay a thin polymer screed using Ronafix mix A @ min. 6mm thick - Ronafix Floor Screed
