Which of the following is NOT classified as Type A soil?

Type A soil is classified as the most stable classification of soils and typically includes cohesive soils that exhibit a high compressive strength, such as clay. The key characteristics of Type A soils are that they have excellent stability, are cohesive, and can support a significant amount of weight without collapsing.

Cohesive soils with high compressive strength fall squarely into this classification as they can hold together well under pressure. Cemented soils like caliche are also strong and stable enough to qualify as Type A due to their hardened structure. Clay loam, being composed of both clay and loam, also possesses cohesiveness, which supports its classification as Type A soil.

On the other hand, soil that is fissured is likely to have compromised structural integrity, which does not support the cohesion and stability characteristic of Type A soil. Fissures can lead to increased risk of collapse, making it unsuitable for classification as Type A.
