recommend a quarry inspection and approve the quarry before manufacturing any rock for the project

stockpile approval (evaluate size, weight, shape, specific gravity) at the quarry and check size again after transportation to the site to check for breakdown in transit

Soundness: check for absorption and run chemical soundness tests as well as wetting-drying test
freeze - thaw test might be necessary depending on your climate



For testing and QA / QC, recommend the following reference which covers the subject well:

thank you so much

I just looked at our (VDOT) specs for riprap. We'd require T113 (coal and lignite, deleterious materials), T112 (clay lumps, deleterious materials), T96 (LAA), T103 and T104 (soundness, magnesium and freeze-thaw).

We have criteria for each of these tests and the rock will comply with these criteria, or be rejected. We'd also do a mine/quarry/pit inspection as there are criteria for the pit too.

Our road and bridge specs are on the internet.

f-d

yea as expected these tests are mentioned everywhere, thank you
