As part of a site investigation program for a residential development project you retrieved four different soil samples. None of the soils appear to be organic. At your laboratory you performed grain-size analyses and Atterberg limit tests on the samples. The grain-size distribution data for the four soil samples are shown in Figure below as curves H, I, J and L. From your Atterberg limit tests on the portion of soil I, LL=41 and PL=18. a. Determine the AASHTO group classification and group index for soil I using the data given above. b. Determine the USCS group symbol and group name for soil I using the data given above.
