The result of sieve analysis of three soils is given next. It is required to classify these soils according to the AASHTO Classification System. Use the attached AASHTO Classification of Highway Subgrade Materials Table.

What is the classification of Soil B? What is the classification of Soil C? EDI

The sieve analysis of ten soils and the liquid and plastic limits of the fraction passing through the No. 40 sieve are given below. Classify the soils using the AASHTO classification system and give the group indexes. % Passing No. 10: 92 % Passing No. 40: 75 % Passing No. 200: 62 LL = 43 PL = 28 Group classification: Blank 1 Group index: Blank 2 Blank 1 Add your answer Blank 2 Add your answer

I am working on a lab report for a sieve analysis that was conducted in the lab. I got that the soil was made up of approximately: 20.5% gravel, 77.8% sand, and 1.7% fines. The values for the coefficient of uniformity (Cu) and coefficient of gradation (Cc) are 10.56 and 0.528 respectively. What does this mean when it comes to engineering design? Would the soil be considered good for building a structure? If so, is there a specific type of structure that would work best with this type of soil?
