Samenvatting
Intrusive investigations have shown that in many post-tensioned segmental bridges, the post-tensioning systems are in good condition, but some contain significant faults - singly or in combination - such as large voids, moisture, salts and corrosion of stressing tendons. Measures aimed at improving the design, detailing, specifications, materials, construction methods and testing for grouted post-tensioned concrete bridges are discussed in this paper. Adoption of these measures will significantly improve the durability of these bridges in the future.
