EXPLAIN EVERY PART AND DO CALCULATIONS BY HAND ON PAPER. Consider the six soils whose characteristics are presented in the tables below:

TABLE $1$: GRADATION AND ATTERBERG TEST RESULTS

Plot gradation curves for soils A$,$ B$,$ C$,$ D$,$ and E$.$ The gradation curves are to be plotted

using plotting or spreadsheet software and formatted in a manner similar to the example

plot provided. Note that Sieve Numbers $20$ and $60$ are not marked on the plot and should

be included in the template you create. $($This template will also be useful for your future

laboratory report.$)$ Clearly label each soil on your plot.

Classify each of the six soils $($A through F$)$ by the Unified Soil Classification

System $($USCS$).$ Include both the group name and group symbol in addition to providing

support for your reasoning for each classification.

After classifying the six soils using the USCS, classify each of the soils by the American

Association of State Highway and Transportation Officials $($AASHTO$)$ system. Include

the group classification, group index, and the general rating of the soil as a potential

pavement subgrade.
