AASHTO classification is primarily used for highway construction and is based on the physical properties of soil. USCS classification is more widely used and is based on both the physical and engineering properties of soil. AASHTO provides more detailed guidance for highway design and construction compared to USCS.

What type of tests does a competent person need to perform in order to classify soil?
A competent person would need to conduct tests such as sieve analysis, hydrometer analysis, Atterberg limits tests, moisture content determination, and soil classification tests based on the Unified Soil Classification System (USCS) or AASHTO classification system to accurately classify soil types.
How are some of the soil gradations classified?
Soil gradation is a type of classification that ranks coarse soil based on the size of its particles. Soil gradation is found by studying the results of a sieve analysis or a hydrometer analysis.
What is the difference between pedon and soil profile?
A pedon is a 3-dimensional unit of soil used for classification, typically about 3 feet wide, 3 feet long, and extending to the depth of the root zone. A soil profile, on the other hand, is a vertical section of soil layers from the surface down to the parent material, displaying the soil horizons and characteristics at a single location. So, a pedon can represent a portion of a soil profile.
What is the study of soil science?
Soil science is the study of the composition, formation, classification, and mapping of soils; their physical, chemical, and biological properties; the interactions between soil and plants, animals, and the environment; and how soil can be managed sustainably for agricultural, environmental, and engineering purposes.
What is Difference between raw soil and baked soil?
Raw soil is natural soil that has not been altered or processed in any way. Baked soil is soil that has been heat-treated to remove any organic matter, pathogens, or contaminants, making it sterile and free from any living organisms. Baking soil can also alter its physical properties such as structure and nutrient availability.

What is the difference between a pedon and a soil profile?
The soil profile is the section of soil going down vertically. Soil pedon is a portion of soil which used for studying.
What is the difference between soil profile and soil horizons?
A soil profile is the section of soil going down vertical, while soil horizon is the section of soil going horizontal.
What are the classification of soil?

The difference between oxic and anoxic soil?
Soil that contains oxygen is known as oxic soil. On other hand soil which lacks the oxygen is known as anoxic soil
