PSI - Issue 84

1022 Ivan Beltracchi et al. / Procedia Structural Integrity 84 (2026) 1015–1022 cracking / eq is 2.18, providing a useful reference point for identifying unusually low ratios (related to the heaviest vehicles) and assessing variability across the events. The proposed methodology represents a practical, transferable workflow for national bridge assessment frameworks, supporting risk-based asset management. Acknowledgements The authors wish to express their gratitude to iWIM s.r.l. for providing all the instruments and to the Province of Brescia to let us conduct this important ongoing research on the bridge. Special thanks are also extended to the CN MOST Spoke 7 and PRIN projects for financing these nationally relevant activities and to all the people involved. The Authors gratefully acknowledge the entire working group, including asphalt research group of University of Parma (Prof. Gabriele Tebaldi, Prof. Elena Romeo and Ph.D. Haitao Ge), Nico Di Stefano, Enrico Faccin, Luca Facconi and Stefano G. Mantelli for sharing valuable ideas that are contributing to the continuation of the research.
