Problem 3: Soil Classification using the AASHTO and USCS Systems
(you will need to use the charts provided within the classification lecture)
A. Classify the soil according to the USCS classification system:
%passing sieve No. 4 - 86%,
%passing sieve No. 200 - 12%
PL =26%, PI = 10%
Dio (mm) = 0.1, Duo (mm) = 0.32, D. (mm) 0.9
B. Classify the soil samples A, B, and C below using the AASHTO and USCS Systems.
