Sir i have question that how will we calculate the applying roller weight and num of roller passing from proctor test are other test..please reply me iam waiting for ur response
It is standard for each type of test like for Standard Proctor test weight of hammer is 2.495 kg , 3 layers of soil and 25 number of blows for each layer , free fall of hammer is 12 inch i.e. 304.8 mm.
U should calculate the amount of compactive energy in kgm/m3 applied in the case of heavy or light compacttion, anyone which is needed... After that u calculate the compactive energy appllying by roller in one pass which can easily be calculated by given datas. Then u multiply it to 'n' the no. Of passes. And equate both u can get no. Of passas. Be careful about units
Sahi hai i just have started this lecture i like this and give lectures for other subjects also
Nd sir for better strength and stability the fine grained soil nd coarse grained soil are compacted ?
A-Dry of omc &B- wet of omc
Sir which side have more permeability? Dry of optimum or wet of optimum?
Sangeetha Joshy wet side of optimum will have more permeability

Nd sir when we increase compactive effort ,omc and max dry denisity decreases..
Sir ye smj nhi aaya dry of omc and wet of omc
