Popis:	In order to predict the weathering process of rock foundation and rock materials for engineering purpose, fundamental studies have been carrying out to investigate the factor of weathering, changes of some properties and rock deterioration mechanism by weathering.The outdoor exposure tests on Cretaceous Granitic Rock (Kitakyusyu granite) were carried out in this study. The columnar specimens used in this experiment are composed of a series of rocks that include fresh rocks to weathered rocks. Their weathering properties were clarifed by the outdoor exposure, and the regression equations for the deterioration process were obtained as a function of outdoor exposure time. Using these equations, one can predict the weathering process from the initial physical and mechanical indices of rocks.
