Using the Unified Soil Classification System classify the following three soils: Sieve size Soil 1 Soil 2 Soil 3 % finer % finer % finer No.4 99 97 81 No.10 92 90 70 No.40 86 40 49 No.100 78 35 No.200 60 4 32 LL (%) PL (%) 42 40 60 20 30 28 Cu 34 1.8 800 1.6 0.95 0.2 Note: gravel size is defined by particle size between 4.75mm (#4 sieve) and 75mm. Equation of A-line: Pl = 0.73 (LL - 20%).

Classify all the soils in 5.8 using unified soil classification system. Give group symbols and the group names

How to solve 5.6 part A & B

The sieve analysis data for a granular soil are given below. % passing or finer 19 mm sieve = 100%% passing or finer 4.75 mm (4 sieve) = 61%% passing or finer 0.075mm (200 sieve) = 16% What are the percentages of gravels, sands and fines within this soil, based on the Unified Soil Classification System?

Classify the following soils by the AASHTO classification system. Give the group index for each soil.

Classify soils A, B, C, and D based on the USCS (ASTM D2487 – 17) indicating the symbol and soil description. Additionally, classify the soils according to the AASHTO Soil Classification System indicating the name of the soil group as well as the GI.
