Abstract
The bearing capacity characteristics of compacted soft rock materials are examined based upon the results of some laboratory tests such as a slaking and a crushing tests and CBR test, etc. As a result, it is revealed that the relationship between CBR and air-porosity of a specimen is unique and specifies the critical air-porosity, and the bearing capacity of a specimen is mostly affected by the material properties and the degree of repetition of dry - wet conditions. Moreover, it is shown that the characteristics of critical air-porosity have close contacts with the material properties.
