The preservation and assessment of the historical infrastructures, particularly masonry bridges, is crucial in safeguarding heritage and promoting sustainable development. This study focuses on the characterisation of the Joncadella Bridge, employing a combination of non-destructive and minor destructive testing techniques, alongside historical documentation analysis. Through examination of historical records, geometrical survey, and pathology assessment, insights into the construction details and materials used in the bridge's construction were gained. Non-Destructive Testing (NDT) methods such as thermography, magnetometry, ultrasonic pulse velocity, and the rebound hammer test were utilized to assess structural integrity. Additionally, Minor Destructive Testing (MDT) techniques including the pin penetration test, helix screw pull-out test, and torque penetrometric test were employed to evaluate mechanical properties of materials. Furthermore, laboratory experiments involved mortar identification, and mechanical characterisation of stone and brick samples. The obtained data will be used to feed analytical models of the bridge, aiding engineers in assessing structural performance, identifying vulnerabilities, and formulating maintenance strategies. This comprehensive approach, integrating historical research with different types of testing methodologies, can provide valuable insights into the condition and behaviour of masonry infrastructure, facilitating effective preservation strategies. The study emphasizes the importance of combining quantitative and qualitative analyses, thereby contributing to the advancement of methodologies for masonry infrastructure characterisation and conservation.
