solu on RATED A+ 2025/2026 NEW!!
Soil Compac on - Ans Densifica on by removal of air instantaneously
Soil consolida on - Ans Removal of water in saturated condi ons, me dependent
Purposes of Soil Compac on - Ans Increased shear strength, s ffness
Improved quality control, erosion resistance
Decreased hydraulic conduc vity, liquefac on poten al
To determine the DRY unit weight: - Ans 1. Measure TOTAL unit weight
2. Measure w, moisture content
3. Calculate yd = y/(1+w)
Rela ve Density - Ans Dr = (emax - e) / (emax - emin)
Compac on Curve - Ans X axis: Water content
Y axis: Dry Unit Weight
Creates an upside down parabola shape
Standard Proctor Test - Ans Plot points on compac on curve. The peak is the max yd and
op mum water content
Modified Proctor Test - Ans Plot points on compac on curve. The peak will have a higher max
yd and lower op mum water content than STANDARD.
