Paving base - is deco granite any good?

Hi,
I'm going to pave an area roughly 100m2 which including around the swimming pool and pathway leading in/out of the house to the backyard. Some guy in the brickyard suggested deco for base since the area will be low-traffic. I've got about 2/3 of the area already covered in a good 50-60mm thick of deco (leftover from pool and concreting jobs). It'll be a pity just to scrape them all off and replace with road base. So can I just top up the deco + allowance for compaction to 100mm as the paving base?

Thanks:2tsup:

paving the first time - Al

Its not ideal because it continues to breakdown. The mica content will eventually form clay - if my limited geology is correct. However the quartz & feldspar content is fine. It also has excellent gap-gradient, particle size so compacts very well

So.... if it was me ...I would use it, but I would mix crusher dust (basalt) through it with about 5 bags of cement and compact the living daylights out of it.

I recon it will be fine.
