What does the term 'granular material' typically refer to in the context of soil and aggregate testing?

The term 'granular material' in the context of soil and aggregate testing generally refers to a mixture of granular soil types that can include both fine and coarse particles. This term encompasses a wide range of materials that possess a grainy texture, including sands, gravels, and other similar materials.

Granular materials are often characterized by their ability to drain water well and their lack of cohesive properties, making them significant in engineering and construction applications. The inclusion of different types of granular soil ensures a balanced mixture that can provide stability and strength for various engineering purposes, such as in the construction of pavements, foundations, and embankments.

Recognizing that granular materials can consist of various soil types is crucial in testing and analysis, enabling accurate assessment and application in real-world scenarios. This blend of different granular materials contributes to the overall performance and reliability of construction projects.
