What is the minimum soaked CBR value specified for Item 202?

The correct minimum soaked California Bearing Ratio (CBR) value specified for Item 202 is 80%. The CBR test is a measure of the strength of subgrade soil and is particularly important in civil engineering and materials engineering for determining the load-bearing capacity of the ground for pavement design.

An 80% CBR value indicates that the soil has a good bearing capacity to support structural loads, ensuring that pavements or structures built on top of it will have adequate stability and performance under expected traffic and environmental conditions. The chosen value reflects industry standards and practices for high-quality materials, ensuring safety and longevity in construction projects.

In the context of engineering, a CBR value of less than 80% may not provide sufficient support for the intended structures, leading to potential failures or excessive maintenance over time. Therefore, adhering to the specified minimum CBR value is crucial for achieving optimal performance in pavement design and to ensure the reliability of the materials used in construction.
