During the physical test, the material passing which sieve is separated into two parts?

The process of separating material passing through a specific sieve into two parts is essential in aggregate testing, particularly for understanding the gradation and characteristics of the aggregate. When material is passed through the 2.00 mm sieve, also known as the No. 10 sieve, it separates the material into two distinct fractions: the material that is finer than 2.00 mm and the material that is coarser than 2.00 mm. This separation is crucial for various testing protocols, as it allows technicians to analyze the finer fractions and the larger particles separately to determine their individual properties, such as gradation, compactability, and structural integrity.

By focusing on the 2.00 mm sieve, it plays a critical role in understanding the overall makeup of the aggregate base material, particularly in applications for construction and paving, where precise aggregate characteristics are vital for performance and durability. The other sieve sizes listed serve different purposes and do not contribute to the same separation into two distinct parts as the 2.00 mm sieve does.
