Question: Mold dimensions: Diameter ( d ) 4 ? in Height ( h ) 4 . 6 in Volume of mold in { : ? 3

Mold dimensions: Diameter (d)4? in Height (h)4.6 in
Volume of mold in {:?3)=(4)d2h=57.81 in =57.81in31ft3=.03in3ft3(1ft3=1,728in3)
Wet Density,
Moisture content, MC or (%)=(Massofwetsoil-MassofdrysoilMassofdrysoil)100
Dry Density, d(lbft3)=1+
Zero-air Void Dry Density, d(zmsx)(lbft3)=Gsw1+Gs
Assume specific gravity, Gs=2.65 and density of water, w=62.4lbft3 Assessment Questions:
Complete all sections of your lab report as described in the syllabus, lab-grading rubric, and
outline of lab report (sample)- individual lab report
Draw the compaction curve (i.e., plot the dry density values on the y-axis and the moisture
contents on the x -axis). Draw a smooth curve connecting the plotted points. Plot the zero-air-
void line on the same graph.
Note: This Graph should look like the "Compaction Curve" on slide 17 of Lecture 7(soils)
slides.
Identify and report the optimum moisture content (OMC or opt) and the maximum dry
density (MDD or Pd(max)). The optimum moisture content (OMC or opt) is the water content
that results in the greatest dry density for a specified compactive effort.
