Thanks for the input everyone, my main goal here is to improve the quality of our proctor curves to account for these situations where the materials dont behave as expected. My supervisor wants to see perfect curves on everything, which in my opinion isnt always obtainable for certain material...
If I'm understanding you correctly the excess water that escapes the mold is a result of over-saturation and the soil cannot absorb the excess water. If this is the case, is there any reason to try and pound a point on material overly saturated?
Thanks Ron, the moisture content that I am using to plot the curve is strictly what is determined through oven-drying the sample.
The pre-compaction moisture contents are being used as only an estimate for what to expect after oven-drying for quality control.(i.e. if a tech obtains actual...
When performing Modified Proctor Testing of soils, I am sometimes seeing odd results for the wettest test point. For example, I will add water for ~10.0 moisture to obtain . When pounding the Proctor "pumping" will begin to occur. Usually by the 4th & 5th lift, muddy water will "bleed" out the...
