This video focuses on questions related to Geotechnical engineering.
The top 500 mm of a site consists of clayey sand with a void ratio of 0.90 and a water content of 20%. The specific gravity of the soil grains is 2.68. Determine the moist unit weight of the soil.
When the ground is compacted at the same water content, there is a 45 mm reduction in the thickness of this layer. Determine the new void ratio.
