Textbook Problem

The relative compaction of a clayey sand in the field is 90%. The maximum and minimum dry unit weights of the sand are 115 lb/ft3 and 93 lb/ft3, respectively. Determine:

a. Dry unit weight in the field

b. Relative density of compaction

c. Moist unit weight at a moisture content of 18%

(a)

To determine

Find the dry unit weight in the field.

Explanation

Given information:

The relative compaction of clayey sand (R) is 90 %.

The maximum dry unit weight of the silty sand γdmax is 115lb/ft3.

The minimum dry unit weight of the silty sand γdmin is 93lb/ft3.

Calculation:

Determine the field dry unit weight (γd(field)) using the relation.

R=[γd(field)γd(max)]

Substitute 90 % for R and 115lb/ft3 for γd(max)

(b)

To determine

Find the relative density of compaction.

(c)

To determine

Find the moist unit weight.
