Abstract
The relative compaction (RC) parameter is commonly used for assessment of the degree of compaction of existing fill slopes and (or) for the design and construction of new fill slopes. This technical note presents the results of an experimental study on the relationship of RC with the saturated hydraulic conductivity (ksat) of typical completely decomposed granite (CDG) in Hong Kong. The results are interpreted and discussed. Useful correlations of RC versus ksat and void ratio (e) versus ksat are obtained. It is found that the RC has a significant influence on ksat of CDG. The influence of RC is equivalent to the influence of e on ksat of the soil.
