  Chapter Three - Granular Base and Subbase …

  Sample the aggregate subbase at the time it is deposited on the roadbed. Observe delivered aggregate subbase to assure that it is clean of debris and other harmful materials. For requirements related to material quality, perform the tests at the frequencies shown in Section 6-1, “Sample Types and Frequencies,” of this manual.

  Geotechnical and Geoenvironmental Properties of Recycled Construction ...

  2012829 · In terms of usage in pavement subbases, RCA and WR were found to have geotechnical engineering properties equivalent or superior to that of typical quarry granular subbase materials. CB at the lower target moisture contents of 70% of the OMC was also found to meet the requirements of typical quarry granular subbase materials.

  Best Fill Under Concrete Slabs - Gravel Subbase - Concrete …

  Concrete strength also comes into play, but most slab concrete is around 3000 to 4000 psi, so it's not a major factor. The tensile strength of concrete is typically taken as 10 to 15% of the compressive strength, so only about 400 or 500 psi. Compare that to the tensile strength of Grade 60 rebar, which is 60,000 psi.
