The process of giving natural soils
enough abrasive resistance and shear
strength to accommodate traffic or
design loads is called

Answer 18

ground
modification or soil stabilization.

Question 19

is the process of increasing the density of a soil by mechanically forcing the soil particles closer together, thereby expelling air from the void spaces in the soil.
