WebbThe Plastic Limit(PL) is the moisture content at which a fine-grained soil can no longer be remolded without cracking. The Shrinkage Limit(SL) is the moisture content at which a fine-grained soil no longer changes volume upon drying—any loss of moisture is compensated by the entry of air into the pores. Webb21 maj 2024 · Meanwhile, the plastic limit is calculated by an experiment that is not standardized and can be affected by the operator’s experience. In this case, the important parameters that affect the soil behavior are obtained in a wide range of values, and the reliability of the results is debatable.
