In order to evaluate quantitatively and to measure by a non-contact method for degree of deterioration of concrete surface subjected to freezing and thawing action, this study investigated applicability of an arithmetical mean deviation to measurement of scaling. The arithmetical mean deviation was useful method for quantitative evaluation of measurement of scaling regardless of mix proportion, curing and experimental condition in this study, and also the measurement condition had little effect on the results of the mean, from laboratory experiments and investigation for existing actual structures. Relationships between the mean deviation and distribution of the crack density from the surface to inside of concrete cover were also discussed, thus it was revealed that the micro cracks were propagated up to 30 mm depth from the surface showed scaling. Furthermore, attempts of simplified measuring of the arithmetical mean deviation by using the stereo-camera were carried out. Evaluation of deterioration of concrete surface by using the arithmetical mean deviation was applicable satisfactory from the results of this study.
