Pre-graded samples for soundness and abrasion are a cost saving option if you are testing for routine quality control reasons. If you are testing due to serious quality issues or failures, samples should be in bulk and as representative of the source as possible. Information about pre-graded weight requirements can be found on the Spec Sheet (pdf).  Click here to download our testing price sheet (pdf).

For 1 - 3 tests per sample, use the following as a guide:

Coarse Aggregate: 50 - 100 lbs
