state gov TSPSC Polytechnic Lecturer Mock Test 2022 Soil Mechanics and Foundation Engineering Compaction
The compaction of an embankment is carried out in 400 mm thick layers. A rammer is used for compaction that develop energy per drop of 40 kg m. Assume that the foot area of rammer is 0.05 m2 and there is an efficiency of 80% due to non-overlap of rammers, the number of passes required to develop compactive energy equivalent to IS light compaction test is
