A saturated soil has the followingcharacteristics:Initial Volume = 25 cm3Final Volume = 16 cm3Mass of wet soil = 45 gMass of dry soil = 31 ga) Determine the Shrinkage Limitb) Determine the Shrinkage Ratioc) Determine the Specific Gravity of the soil
Classify the following soil by the Unified Soil Classification System. Percent passing No. 4 sieve = 82Percent passing No. 10 sieve = 71Percent passing No. 40 sieve = 64Percent passing No. 200 sieve = 41Liquid limit = 31Plasticity index = 12
1. The compaction requirement fpr clay soils in traditional applications is 90 to 95 % of maximum drydensity at compaction water contents on both sides of optimum, whereas landfil1 clay linerspecifications normally require 90 to 95% of maximum dry density at compaction water contents onlyon the wet side of optimum water content. Why?
The soil at a borrow area is at moisture content of 8.5%and unit weight of 17.5 kN/m3. This soil is used in the construction of a compacted road base where the dry unitweight is 19.5 kN/m3 and the moisture content is 14.0%. Ifthe finished volume of the road base is 120,000 m3, whatwould be the volume of the soil removed from the borrowpit? How much water would be added to the soil from theborrow pit?
