How flat should flat be ?

Sounds daft dunnit? But in the context of making a flat footpath, not so silly.

 

Build up so far

  • MoT1 thoroughly compacted over four years
  • Crusher Run 64mm to dust whacked flat - ish (about 100mm deep)

Have a look at this to see what I mean

The desired cross-fall ( left to right) is shown by the yellow line beneath the level. Thats as I want it almost.

 

The red lines show where, when you look carefully across the compacted base ,  you can see the edges of the barrow-load dumped on the spot. It shows as a sort of flattened ripple. As I understand it, the next layer should be sharp sand (20mm approximately) .

 

Using the sharp sand, will it be possible to 'iron out' the slight dips in the compacted crushed stone layer? Or do I have to scabble it loose until that layer is completly flat , recompact and then lay the sand?

I'm beginning to think I'm addicted to painfully steep learning curves.
