Viaduct in A59 (case study)

This project is about the monitoring of 19 viaducts in and over highway A59 in the Netherlands. These viaducts are all made of reinforced concrete and are build in the 60-ies.

Object analysis

The aim of the project is to follow in time the deformations in the viaducts. These results are not used for structural calculations, but to get more insight in the behavior of the viaducts.

Case type

Object state

The development of the expansion of the decks of the viaducts, due to ASR, is measured with sensors. Both in vertical direction (thickness of the deck) and in horizontal direction (width of joints at the ends of the deck).

Observed deterioration processes

:

Alkali aggregate reaction

Observed damage types

:

Excessive deformation, Cracks

Performance indicators

:

Deformation, Displacement
