Which description fits Type-B soil?

Type-B soil is characterized by having a moderate to less significant load-bearing ability compared to Type-A soil. The correct description that fits Type-B soil includes materials such as angular gravel, silt, silt loam, and sandy loam. These types of soil typically have better drainage properties and allow for more moisture retention than coarser soils, contributing to their classification.

Angular gravel and silt are particularly important in defining Type-B soil, as they often indicate a balance between cohesion and drainage capabilities, making them suitable for supporting construction projects while allowing for some flexibility in adherence to structural safety and stability requirements. The presence of these materials also implies a certain degree of compactness and consistency when assessing soil behavior under load conditions.

By contrast, other options may include soil types that fall outside this classification or are generally considered to have different properties that do not align with the characteristics of Type-B soil. Understanding the composition and behavior of Type-B soil is crucial for those involved in collection system maintenance, as it directly impacts the design and implementation of infrastructure.
