What is the maximum allowable percentage for LL of Item 201?

To determine the correct maximum allowable percentage for LL (Liquid Limit) of Item 201, it's important to reference standards or specifications that are relevant to the classification of materials, particularly in the field of civil engineering and materials testing.

The Liquid Limit is a crucial property of fine-grained soils, used to assess their plasticity and behavior under various moisture conditions. It also plays a significant role in classifying soil types according to standards like those of the Unified Soil Classification System (USCS) or ASTM D4318. In many engineering applications, the specified limits for the Liquid Limit keep the material within a manageable range to ensure stability and performance in construction.

In this particular scenario, a maximum allowable percentage of 25% for LL suggests that it is a balance between retaining adequate workability and ensuring that the soil or material being used does not exhibit excessive plasticity, which can lead to complications such as increased deformation or instability in constructions.

The chosen percentage reflects established guidelines, making it a practical benchmark for various engineering applications. Therefore, a Liquid Limit over this threshold could potentially indicate problematic materials that would not perform as intended under load or wet conditions.
