Backfilling material for driveway?

[swiftgti]

Hi all,

I've been digging out the front garden and had the soil taken away in a skip, however our plans have changed slightly and I now need to raise the dug out area by an inch or two.. Before laying the MOT and finishing gravel.

What is the best material to use to top the level back up, so that it won't affect the stability of the driveway sub base?

Slightly more mot?

I did think that but wondered if there was a point where too much MOT would have an effect on the stability?
As I've already allowed a good 200mm for the sub base.

MOT will be fine - just make sure that it's well consolidated
