Question

: In a construction site containing only cohesionless soil deposit, how relative density is determined? Also, suggest a remedial method to improve the density index of that site if the relative density is poor.

Answer 1

● Relative density can be calculated as the ratio of difference of void ratios of cohesionless soil in its loosest state and the natural state (emax – e) to the difference between void ratio in its loosest and densest state (emax – emin). Relative density determines the compactness of the cohesionless soil.

Id = (emax – e) / (emax – emin)

● Remedial method for improvement of the density index of the site if relative density is poor is doing compaction of the site either by rollers or vibrators or rammers which is suitable.

if helpful pls give?.

thank you.
