Florida Agricultural and Mechanical University Division of Engineering Technology Soil Mechanics & Foundations ETC 3211 Assignment 3-1 1. The following are the results of a sieve analysis. Determine the percent finer than each sieve and plot a grain size distribution curve. The related empty gradation pages are provided. Cumulative Percent of Mass retained on Each Percent Mass retained on Each Sieve(g) U.S. Sieve Opening # Percent Finer (mm) M₂ Sieve(g) R₂ 100 - ΣΚ.

Based on the grading curve of the soil: (a) Determine D10, D30, and D60 from the grain-size distribution curve. (b) Calculate the Uniformity Coefficient. (c) Calculate the Coefficient of Gradation. (d) Calculate the percentage of Gravel, Sand and fine-grained soil according to USCS and AASHTO systems
