Abstract: Provided is a damage evaluation apparatus capable of evaluating the damage of an asphalt mixture or the like non-destructively for a short time and in a precise manner. This apparatus turns a sample (S) and irradiates it at every predetermined angle with an X-ray so that it detects the transmitted X-ray with an X-ray detector (104). An image reconstruction unit (122) creates multiple sheets of slice image data reconstructing the inside state of the sample (S) by using the detection results of the X-ray detector (104). An image processing unit (124) creates three-dimensional CT image data of the inside of the sample (S) with the slice image data created by the image reconstruction unit (122). A cavity analyzing unit (126) calculates the quantitative data of the inside state of the sample (S) with a predetermined calculation algorithm by using the slice image data created by the image reconstruction unit (122).

Abstract: A testing device which makes structure of equipment simple, achieves dwarfing and lightening and can improve precision of measurement of tested material. And method to implement test of strength of fracture, fracture temperature, strain at fracture, viscosity and stress relaxation (relaxation modulus) and so on of test piece handily.
