The literature contains numerous equations linking a soil's characteristics of compressibility to its index properties, such as liquid limit and plasticity index. As these equations are often used to obtain preliminary evaluations of the compression index Cc, it is important to know the reliability of these equations. The paper analyses some of the equations more frequently used to calculate Cc from laboratory index properties, using a methodology based on two specific indices: ranking distance and ranking index. Forty-six samples formed the data set, mainly of Blue Clays and Varicoloured Clays outcropping in the southern part of the Bradanic Foredeep. It was concluded that the most reliable equation correlates Cc with the shrinkage index.

Abstract
The literature contains numerous equations linking a soil's characteristics of compressibility to its index properties, such as liquid limit and plasticity index. As these equations are often used to obtain preliminary evaluations of the compression index Cc, it is important to know the reliability of these equations. The paper analyses some of the equations more frequently used to calculate Cc from laboratory index properties, using a methodology based on two specific indices: ranking distance and ranking index. Forty-six samples formed the data set, mainly of Blue Clays and Varicoloured Clays outcropping in the southern part of the Bradanic Foredeep. It was concluded that the most reliable equation correlates Cc with the shrinkage index.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
