Problem $2(30\%)$

Hint: To solve this problem, you first have to do the same granulometric analysis that you did in the laboratory, but this time with the data from the table above. USCS: If more than $50\%$ of the material passes through the No$.200$ sieve, the soil is classified as fine$-$grained $($either silt or clay$).$ AASHTO: If more than $35\%$ of the material passes through the No$.200$ sieve, the soil is classified as fine$-$grained $($either silt or clay$).$ In both systems, the material retained on the No$.200$ sieve, meaning it does not pass through, is classified as either gravel or sand.

For the rehabilitation and construction of a bridge, a sample of the prepared granular base was taken for

classification according to AASHTO. The results of the sieve analysis are as follows:

a$)$ Calculate the percentage passing through each sieve.

b$)$ Plot the particle size distribution curve.

c$)$ Classify the soil based on AASHTO, noting that the soil has no plasticity index $($P$1).$
