Hi all

Have some public car parks to resurface, in the region of 2000m2 each.  For the most part, the existing sub-base is fine and it's just the surface course that is worn/fretting/crazing etc.  Have often cut chases to the perimeter and overlaid the entire area with 40mm depth of HRA or SMA.  However, is it worth considering surface dressing as a cheaper alternative?  My concern with this approach has always been that a thin surface dressing would not stand up well to the regular harsh slewing action of tyres in a car park - is there truth in this?  So, in a nutshell, I'm interested in technical and price comparisons for the two different approaches - asphalt overlay and surface dressing (specifically in car parks, not on the carriageway/footway).

I'd speak to Colas contracting or Kiely Bros or Coldmac and ask their advice and price.

They are micro-asphalt experts and are all laying their materials on heavily trafficked roadways.
