In the modified Proctor test, what is the weight of the rammer used?

In the modified Proctor test, the rammer used has a weight of 4.54 kg (10 pounds). This test is essential for determining the moisture-density relationship of soil, which helps to assess compaction specifications for various construction applications. The use of a heavier rammer in this test, as compared to the standard Proctor test, is intended to simulate the increased compactive effort that's typically experienced in field condition scenarios where higher soil densities may be required. This increased weight ensures that the results accurately reflect the performance characteristics of the soil when subjected to similar conditions during compaction on a job site.
