Life cycle cost analysis for joint elimination retrofits and thermal loading on Colorado bridges
MetadataShow full item record
Bridge expansion joints are a particularly troublesome component of bridges and many Departments of Transportation (DOTs) are looking for a solution to deteriorating expansion joints on highway bridges. Bridge expansion joints create a break in the structural continuity of a bridge allowing clogging gravels and corroding chlorides to enter. They are designed to absorb thermal movements of the bridge between two bridge elements. There are three main issues regarding expansion joint: maintenance, knowledge about thermal movements, and costs. In order to prevent deterioration due to expansion joints ...
