Step 1 – First, the aggregate sample sieve through 12.5mm sieve and collect it which is retained in 10mm sieve. Step 2 – Now, the sample should be dried through the oven up to 4 hours at 100 deg to 110 deg. Step 3 – Then, the aggregate sample should be filled in the metal cup by 3 layers. Each layer should be tamped 25 times by the tamping rod.
