The base course material, according to ACI 302, "Concrete Floor and Slab Construction," should be "compactible, easy to trim, granular fill that will remain stable and support construction traffic." ACI 302 recommends material with 10 to 30% fines (passing the No. 100 sieve) with no clay, silt, or organic materials.
A range of machinery will be needed to construct the base. An excavator will be used to dig down to the correct sub soil material. Your contractor might also bring in a bulldozer for more rapid earth moving. A roller will be used on multiple layers: sub-base, aggregate, stone dust, final footing. The roller should be between 10-15 tons.
