50) A line that shows the relation between water content & dry density for the compacted soil is known as what?
- a) Density line
- b) Air-voids line
- c) Zero air voids lines
- d) All of the mentioned
Answer: b) Air-voids line
• A line that shows the moisture content & dry density relation, especially for the compacted soil containing a constant % of air voids, is called an air-voids line.
• A line that joins points with dry unit weights corresponding to 100 percent saturation at different moisture contents is called a zero air-void line.
