• curprev 17:1017:10, 15 April 2022 Falk-Ramarren talk contribs 6,583 bytes −333 While CH and MH generally have higher plasticity than CL and ML, the H and L in the group symbols are based on liquid limit, not plasticity. If you look at the PDF of the referenced standard in the section titled "Procedure for Classification of Fine-Grained Soils", it states this. Also note that on the plasticity chart a CL can have a higher plasticity index than a CH, but it cannot have a higher liquid limit. Same with ML and MH. Also cleaned up the references. undo Tag: Visual edit
