WebFine soils. Plasticity index. The consistency of most soils in the ground will be plastic or semi-solid. Soil strength and stiffness behaviour are related to the range of plastic consistency. The range of water content over which a soil has a plastic consistency is termed the Plasticity Index (I P or PI). WebThe numerical predictions exhibit that the soil plasticity can significantly influence the response of the roller and the ground settlement level; hence, practicing engineers can consider the soil plasticity index as an influencing factor to interpret the intelligent compaction results and optimize the compaction process.

WebThe AASHTO system uses both grain-size distribution and Atterberg limits data to assign a group classification and a group index to the soil. The group classification ranges from A-1 (best soils) to A-8 (worst soils). Group index values near 0 indicate good soils, while values of 20 or more indicate very poor soils. WebPlasticity index: Plasticity index (PI) is the range of water content over which the soil remains in the plastic state and mathematically defined as, 𝑃𝐼= −𝑃 Liquidity index: Liquidity index indicates the nearness of its water content to its liquid limit.
