Smooth and durable transition structure for long bridges
Published at : 08 Jan 2021
Deformations occur in long concrete bridges due to seasonal temperature changes. The transition structure is built of small concrete elements, spacing out evenly the deformation. A flexible pavement structure absorbs the resulting small gaps, providing optimal driving comfort. Conventional expansion joints made of steel account for 20 % of the maintenance costs of a bridge. The transition structure is durable, there are no maintenance costs at all.
