Damage Evaluation Apparatus, and Damage Evaluation Method

摘要

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). A damage decision unit (128) decides the damage state in accordance with a predetermined decision standard by using the analysis result of the cavity analyzing unit (126).
