Hello everyone, I hope the prep for the FE Exam is going well.

The unified soil classification system (USCS) uses letter symbols to describe soils. The parameters used for classification are:
1. F200= percent passing the No. 200 sieve (opening size = 0.075)
2. Uniformity coefficient Cu
3. Coefficient of curvature Cc
4. R4 = percent retained on the no. 4 sieve (opening size = 4.75 mm)
The AASHTO (American Association of State Highway and Transportation Officials) soil classification criteria are summarized in the FE Handbook under the Geotechnical Engineering section. The soil classification protocol defined by AASHTO utilizes the following criteria:
Percent passing No. 10 sieve (F10)
Percent passing No. 40 sieve (F40)
Percent passing No. 200 sieve (F200)
Liquid Limit (LL)
Plasticity Index (PI)
