Took out a concrete slab... what to fill it with?

[salvas]

I used a jackhammer to demolition a concrete slab on my yard... about 40-60 sq feet or so and 6-8 inches deep it seems.

I need to fill it with top soil + compost?

Any ratios or specifics that i should be alert to? 100% top soil or any other ratio? I cleared the bottom of all the little rocks that i could

Usually it's going to be some mixture of sand and compost. If you've had soil tests interpreted in the past, I would seek specific advice based on those results.
