Pneumatic tyred rollers are used for compaction for _______ soil of low plasticity.
OMC-SP and MDD-SP denote the optimum moisture content and maximum dry density obtained from standard Proctor compaction test, respectively. OMC-MP and MDD-MP denote the optimum moisture content and maximum dry density obtained from the modified Proctor compaction test, respectively. Which one of the following is correct?
Compaction of granular soils are generally done by:
If the permeability, shrinkage and swelling of a compacted soil having same density on dry side of optimum moisture content is compared with compaction on wet side of optimum, the variation in these properties will be
Amount of compaction greatly affects:
In a proctor test, 1.8 kg of moist soil was filled in the mould (volume = 944 cc) after compaction. A soil sample weighting 23 g was taken from the mould and oven dried for 24 hours at a temperature of 110°C. The weight of the dry sample was found to be 20 g. The specific gravity of soil solids is G = 2.7. The theoretical maximum value of the dry unit weight of the soil at that water content is equal to _____
Proctor’s compaction test for the maximum dry density of a certain soil gave the results as: 1.77 gm/cc and OMC 14.44%. The specific gravity of the clay soil grain was 2.66. What was the saturation degree for this soil?
