soil classification

Use the USDA soil classification triangle to determine the textural soil class designations with the distributions of particle sizes shown in the table (unit is mm).

From the particle size distribution curve, about 61% of the oil is finer than 0.074 mm in diameter. The liquid limit and plastic limit of minus No 40 fraction of the soils are as follows: LL =26, PL= 20. Classify the soil using the USCS.a. CL-MLb. CL-MLc. SP-SCd. CH
