Results of a standard Proctor compaction test on a silty sand are shown in Figure 6.40.
Figure 6.40
a. Find the maximum dry unit weight and optimum moisture content.
b. What is the moist unit weight at optimum moisture content?
c. What is the degree of saturation at optimum moisture content? Given: Gs = 2.69.
d. If the required field dry unit weight is 18.5 kN/m3, what is the relative compaction?
e. What should be the range of compaction moisture contents in the field to achieve the above relative compaction?
f. If the minimum and maximum void ratios are 0.31 and 0.82, respectively, what is the relative density of compaction in the field?
(a)
The maximum dry unit weight and the optimum moisture content.
Calculation:
Plot the graph for moisture content versus dry unit weight as in Figure (1).
Refer Figure (1).
The maximum dry unit weight is
(b)
The moist unit weight at the optimum moisture content.
(c)
The degree of saturation (S) at the optimum moisture content.
(d)
The relative compaction for the required field dry unit weight of
(e)
The range of compaction moisture contents in the field to achieve the relative compaction.
(f)
The relative density of compaction in the field.
