We have some lab results that classify soil as SC without corresponding Atterburg limits. The sieve analysis show less than 25% passing a #200 sieve. When questioned how the classification was reached the respons was it was based on field observation. Is it reasonable or possible to discern between an SC and an SM soil with this percentage of fines by visual observation of samples during collection or is lab testing required?
