Define sieve analysis in the context of aggregate testing.

Sieve analysis is a fundamental procedure in aggregate testing that is used to determine the particle size distribution of granular materials, such as soil and aggregates. In this process, the aggregate sample is placed on a series of sieves with different mesh sizes. The material is then subjected to shaking or vibrating, which allows the particles to pass through the sieves based on their size.

By using this method, the distribution of particles across various size ranges can be quantified, often yielding a particle size distribution curve. This information is crucial for various applications in construction and engineering, as it influences the material's properties and behavior in concrete, asphalt, and other construction processes. The results of a sieve analysis help engineers and inspectors determine suitability for specific uses, compliance with specifications, and overall performance characteristics of the aggregates or soil in real-world applications.
