RE: non plastic soils
And according to the required reporting specified in para 18.1.1, "If either the liquid limit or plastic limit could not be determined, or if the plastic limit is equal to or greater than the liquid limit, report the soil as nonplastic, NP." The liquid limit test cannot be performed when it behaves in manner described in the paragraph above. The plastic limit test cannot be performed when a 1/8" thread of the material cannot be rolled in less than two minutes.
So, non-plastic soils do not have a PI value of zero. They have no PI and they are reported as nonplastic.
