Estimate the swelling potential of soils A-F, Problems 2-33 and 2-35. Use both Table 6-2 and Fig. 6.15.
Problems2-35
The soils in Problem 2-33 have the following Atterberg limits and natural water contents. Determine the PI and LI for each soil and comment on their general activity.
Problem 2-33
On five-cycle semilo garithmic paper, plot the grain size distribution curves from the following mechanical analysis data on the six soils, A through F. Determine the effective size as well as the uniformity coefficient and the coefficient of curvature for each soil. Determine also the percentages of gravel. sand. silt. and clay according to
(a) ASTM,
(b) AASHTO,
(c) USCS, and
(d) the British Standard.
