Soil classification based on CPT measurements

When CPT measurements are available, there is a wide variety of classification systems based on the measured cone resistance, friction ratio and pore pressure. Reference is made to specialized literature. 

Some of the most frequently used classification systems are  

Zone Soil Behavior Type Zone Soil Behavior Type Zone Soil Behavior Type Zone Soil Behavior Type 

1 Sensitive Fine Grained 4 Silty Clay to Clay 7 Silty Sand to Sandy Sil 10 Gravelly Sand to Sand
