This paper aims to present a systematic framework for material characterisation assess brickwork masonry arch bridges. An extensive laboratory campaign was carried out characterise and backfill in Initially, the strength Young's modulus of bricks mortar, as well internal friction angle cohesion materials (e.g., crushed limestone puddling clay), were characterised by undertaking small-scale level tests. Then, compressive prisms, unit-to-mortar bond properties tensile strength, cohesion) assessed at component level. Further, large-scale shear box tests identify frictional properties, including interface cohesion, between material. Moreover, both static high-cycle fatigue three-point bending performed on flat arches obtain crack growth stiffness degradation parameters. Outputs from this experimental can be used parameter identification model calibration complex/high-fidelity numerical models developed
