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, new roughness and rutting-based road deterioration (RD) models, The relationship between changes in roughness [International Roughness Index (IRI)] versus time and modulus of resilience (Mr) loss at granular and sub grade layers versus time, CBR of Sub grade, 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 pre flood strategy. Results obtained using two proposed new gradients of IRI & CBR in Year 1 over probability of flooding and ΔIRI in Year 1 over loss in Mr as well as flood consequences provided similar results. Road authorities should consider changing their roads to flood-resilient pavements in the future.
