Which type of barricade is made using cohesive earth fill and must be free from organic matter?

The type of barricade made using cohesive earth fill and which must be free from organic matter is known as an artificial barricade. This type of barricade is specifically designed and constructed for the purpose of providing protection or a barrier in various situations, such as during military operations or construction projects.

Artificial barricades are engineered to ensure stability and effectiveness, which is why using cohesive earth fill is important. Cohesive materials, such as clay, provide the necessary strength and resistance to hold the barricade in place. Ensuring that the fill is free from organic matter is crucial as organic materials can decompose over time, leading to instability and potential failure of the barricade. The integrity of the fill is essential for maintaining the intended protective qualities of the structure.

Other types of barricades, such as natural barricades, are formed by obstacles like hills or existing landscape features without human intervention. Reinforced barricades may involve additional structural components to enhance strength but do not specifically require cohesive fill. Temporary barricades are often used for short-term needs and might not adhere to the same material specifications, especially regarding the use of cohesive earth fill and cleanliness from organic matter.
