Let's plot these points and extract the information from the graph. Here are the coordinates for plotting: Point 1: (9.9, 15.89) Point 2: (10.5, 16.08) Point 3: (12.1, 16.41) Point 4: (13.8, 16.70) Point 5: (15.1, 16.79) Point 6: (17.4, 16.64) Point 7: (19.4, 16.27) Point 8: (21.2, 15.86) Step 1: Set up the graph axes. • Draw a horizontal axis (x-axis) and label it "Moisture Content (w %)". Scale it from approximately 8% to 22%. • Draw a vertical axis (y-axis) and label it "Dry Unit Weight (_dry kN/m^3)". Scale it from approximately 15.5 \, kN/m^3 to 17.0 \, kN/m^3. Step 2: Plot the points and draw the compaction curve. • Carefully mark each of the 8 coordinate points on your graph. • Draw a smooth curve connecting these points. The curve should rise, reach a peak, and then fall. This is your compaction curve. Step 3: Determine the maximum dry unit weight and optimum moisture content (OMC) from the graph. a) • Identify the peak: Visually locate the highest point on the smooth compaction curve. This point represents the maximum dry unit weight. • Read _d,max: From this peak, draw a horizontal line to the y-axis. The value where it intersects is the maximum dry unit weight. _d,max ≈ 16.79 \, kN/m^3 • Read OMC: From the same peak, draw a vertical line down to the x-axis. The value where it intersects is the optimum moisture content. OMC ≈ 15.1\% The maximum dry unit weight is 16.79 kN/m^3 and the optimum moisture content is 15.1%. Step 4: Determine the moisture content for 95% of _d,max from the graph. b) • Calculate 95% of _d,max: 0.95 × 16.79 \, kN/m^3 = 15.95 \, kN/m^3 • Locate on y-axis: Find 15.95 \, kN/m^3 on the y-axis. • Draw horizontal line: From 15.95 \, kN/m^3 on the y-axis, draw a horizontal line to the left until it intersects the compaction curve. • Draw vertical line: From this intersection point on the curve, draw a vertical line straight down to the x-axis. • Read moisture content: The value where this vertical line intersects the x-axis is the required moisture content. Required moisture content ≈ 10.09\% The moisture content required to achieve 95% of _d,max is approximately 10.09%. Got more? Send 'em!
