Dry Sieve Analysis. 500 gm of a dry soil sample is taken. It is then kept in IS sieves arranged in the order as shown in Table 1. Mass of each sieve is weighed and noted before placing the soil sample in them. The set of sieves were then placed in the mechanical sieve shaker and sieved for 10 minutes. The time is recorded.

All the particle sizes are roughly the same size, which is the case in many clear stone products (e.g. #57 stone). The high void content leads to low stability and makes it difficult to compact. Water drains more easily through uniformly graded aggregates. ... Aggregate Sieve Analysis Test is Used to Assess the Aggregate Gradation.
