Abstract
When the soil charged in vessel is tamped by the rammer, the soil temperature rises by heat generation. As a result of this experimental studies, it has been recognized that the rising temperature offers one of the best possibilities of indicating the physical properties of soil particles.
As one of the process of weathering is change of the physical properties of soil particles itself, the rising temperature shall become an material of judgement for the weatherd degree of the decomposed granitic soil.
And so, we tried to measure the rising temperature. The results are as follows:
1. The rising temperature has relation with the other index of judgement for the weatherd degree, for example, the degree of change in qualities of mineral, fine void contents, specificsurface and ignition loss etc.
2. As compared with the decomposed granitic soil of low weatherd degree, the decomposed granitic soil of high weatherd degree get higher rising temperature.
