Main Cable Inspection of Matadi Bridge in Democratic Republic of Congo

Abstract

The Matadi Bridge, a suspension bridge in Democratic Republic of Congo, was completed in May 1983 by the Japanese ODA. For the main cables of this bridge, the wrapping paste and the wrapping wire combination against the corrosion was adopted. In Japan, this combination was found out to be inadequate, and a dry air injection system was introduced. Therefore it was feared that the corrosion of this cable might be found. To examine the present condition, the main cables were unwrapped and investigated at the site. Some corrosion was found as expected. This paper reports this inspection.
