Alkali-silica reaction (ASR) is a major durability problem that results in a very severe deterioration in the portland cement concrete pavement. The deterioration based on ASR in the cement concrete occurs when alkalis from the cement or from an external source react with free silica from certain aggregates to form an alkali-silica gel. A variety of effort has been provided to establish the method to prevent the ASR problem in the new construction and rehabilitate the existing deteriorated pavement sections due to ASR in Korea. It is expected that the placement of BCO can prevent the additional water intrusion into the existing pavement with the aggregate easy to accelerate ASR and stop the additional ASR related distress. The purpose of this study is to establish method for the rehabilitation of the deteriorated pavement caused by ASR of concrete pavement by the BCO with Very Early Setting Latex Modified Cement.
