What is the weight of the rammer used in the standard Proctor test?

The standard Proctor test utilizes a rammer that weighs 4.54 kg (10 pounds). This weight is crucial in ensuring consistency and reliability in soil compaction testing. The specific weight of the rammer is designed to achieve a standard energy level applied to the soil sample during compaction, which is vital for interpreting the results accurately. The 4.54 kg rammer provides a standardized method for determining the maximum dry density and optimum moisture content of the soil, essential for various engineering applications. Understanding the correct weight of the rammer helps technicians perform the test precisely, leading to better quality control in construction projects.
