BRIDGE REHABILITATION

The maintenance and rehabilitation of a bridge structure need to be planned carefully, whatever the causes of its deterioration, to ensure that communication links remain open. This article examines two major projects, in Honduras and in Russia, in which designing and implementing effective bridge repair is critical to restoring a nation's transport infrastructure. Extensive damage was done to many bridges in Honduras after Hurricane Mitch in October 1998. The typical Honduran bridge has a direct or piled foundation, abutments cast in plain concrete, reinforced concrete piers, and a simply supported reinforced concrete superstructure. The most common types of damage were completely destroyed bridges, settlement of piers, and severe cracking or total destruction of non-reinforced abutments after heavy erosion. Improvements suggested for repairs included improved foundations, strengthening of existing foundations, scour and erosion protection, reduction of hydraulic forces on the bridge, and improved detailing of reinforced concrete structures. In Russia, many bridges were built with inadequate resources, so that there is now a large and growing need for their repair, rehabilitation, and reconstruction. Many of the problems are related to insufficient protection of concrete and reinforcement from water and de-icing salts.
