Given a soil sample that is dark in color and clay-like in texture, what inferences can you make about its potential for being used as a subgrade material in pavement?
Show hintHide hint
Consider how organic materials affect soil behavior in wet conditions.
Question 6.
If during the Toughness Test a soil behaves plastically, how might this influence the design of pavement structures?
Show hintHide hint
Think about how deformation impacts the longevity and stability of the pavement.
