What is the significance of test results in the Sieve Analysis?

The significance of test results in sieve analysis primarily lies in assessing how well the aggregate falls within specified gradation bands. Sieve analysis is a method used to determine the particle size distribution of aggregates, which is crucial for ensuring that the material meets the gradation specifications outlined in project documents or standards. Proper gradation is essential in construction as it affects the workability, strength, and durability of the concrete or asphalt mixture.

When the aggregates fall within specified gradation bands, it indicates that they will perform optimally for their intended use. This process helps in achieving a balance between different particle sizes, which contributes to the overall efficiency of the mixture by reducing void spaces, allowing for better compaction, and improving the material's load-bearing capabilities.

The other options, while related to aggregate properties, do not directly pertain to the primary purpose of sieve analysis. Resistance to deformation, chemical composition, and moisture content are important attributes but are evaluated through different testing methods and do not specifically stem from the results of a sieve analysis.
