Question of the day
Test yourself in 10 seconds
One question a day keeps exam stress away. Pick an answer to check it.
Which of the following types of soil have excellent workability as a construction material?
Answer: A. Well graded gravel
Well-graded gravel (GW in USCS) has excellent workability as a construction material for earthworks because it is easy to compact, drains freely, provides good shear strength, and does not swell or shrink excessively.
