Although several studies observed pavement responses after flooding, no detailed quantification has been done to date. This paper has estimated different pavements' performances with flooding to identify flood-resilient roads. This was shown through (1) new roughness and rutting-based road deterioration (RD) models, (2) the relationship between changes in roughness [ International Roughness Index (IRI)] versus time and modulus of resilience (Mr) loss at granular and subgrade layers versus time, and (3) flood consequence results. The comparative analysis on different pavement performances shows that a rigid and strong pavement built to a high standard is the most flood-resilient, which may be adopted as a preflood strategy. Results obtained using two proposed new gradients of IRI (incremental change in IRI, Delta IRI) in Year 1 over probability of flooding (Delta IRI/Pr) and.IRI in Year 1 over loss in Mr (Delta IRI/MrL) as well as flood consequences provided similar results. Road authorities should consider changing their roads to flood-resilient pavements in the future. It is recommended to investigate after flood roads' structural conditions and performances to validate the new ratio values of Delta IRI/Pr and Delta IRI/MrL.
