Properties of High-Plasticity Clays

2018-10-5  High-plasticity clays occur in many areas of Texas and often offer the most economical material alternative for construction of highway embankments. When constructed with proper moisture and compaction control, embankments constructed of

Measuring the plasticity of clays: A review - ScienceDirect

2011-1-1  Research Highlights Plasticity is related to deforming a substance continuously under a finite force. Composition, particle size, organic matter and additives may affect clay plasticity. Several techniques are used to determine the optimal water content of clays. Methods for evaluating the plasticity of water-clay systems were reviewed. A consolidated method for measuring clay plasticity still ...
