Proctor Test with 6 inch mould

[Jameschen6]

When testing a granular material, it required to test portion passing 19mm sieve (26.0mm for Ontario). How much material is needed for the moisture testing for such grain size material? Many times the curve appear in odd shape due to the moisture results. What is your comments

I would use at least 200g, preferably 400g.
