WebProctor Soil Compaction Test Procedure. Take about 20kg of air-dried soil. Sieve it through 20mm and 4.7mm sieve. Calculate the percentage retained on 20mm sieve and 4.75mm sieve, and the percentage passing 4.75mm sieve. If the percentage retained on 4.75mm sieve is greater than 20, use the large mould of 150mm diameter.
