To be honest, the texture is lend from stones1.inc (pigment in T_Grnt17a with 
slight modifications).
The original render had far more less dynamic in colors. I raised it with before 
posting it in order to see more details.

wow, thanks for the references. Gives me good point where to start, even when 
the Dublin reference seems to be basalt (nearly homogeneous black) instead of 
granite.
It happend that I saw some worker's building a cobblestone sideway. Of cause 
they used freshly broken stones. This was probably the main influence I had in 
mind  as I searched for the right look.

I have to play with the parameters of the rigged_mf function to get this 
polished look on top and a little more grainish look inside the ditches.

I'm not sure if a supperellispoid is the appropiate base shape for a "pillowed" 
cube. Maybe I've to blob a sphere with superellispoid or so.
