In this paper, expansion property of concrete bars deteriorated by Alkali Silica Reaction for a long period was evaluated by using Digital Image Correlation (DIC) Method. The concrete bars within expansive glass were cured in 40 degrees water for two months. Digital images taken intermittently in the curing period were used for DIC method. The strain distribution calculated by DIC method showed the properties on ASR approximately. It could be concluded that DIC method with the long period measurement would be a suitable technique to evaluate deteriorations on concrete structures.
