Visual inspection & non-destructive testing of 7 bridges along Abakaliki-Mbok section of route 25/A.343 (LOT 1) and Ikom-Mfum section of route 90/A.4-2 (LOT 2) – Nigeria
The bridges are in reinforced concrete with beams in prestressed reinforced concrete, with the exception of bridge N. 2 which has reinforced concrete beams.
Non-destructive tests and static load testing have been carried out on reinforced concrete and pre-stressed concrete structural elements of the 7 bridges in order to identify the mechanical properties of the materials and any significant state of degradation.
Structural modelling and checks have been carried out to define the possible required strengthening interventions, which have been designed as well.
