| Popis: | An integrated climate-pavement model is presented to predict service performance. A total of 144 scenarios were considered from a combination of different pavement shoulder conditions (0.0 m; 0.5 m; 1.0 m; 1.5 m), water depth levels (3.0 m; 3.5 m; 4.0 m; 4.5 m), varied thicknesses of asphalt surface courses (2.0 cm; 5.0 cm; 10.0 cm), and three rainy periods (above average, below average, average), applicable to the Metropolitan Region of Fortaleza (MRF). In addition, it was considered the MRF climate change predictions for the 21st century (2031-2070) using 5 climate change models based on the CMIP5 (Coupled Model Intercomparison Project) RCP (Representative Concentration Pathways) scenarios 8.5 and 4.5. Without taking into account the climatic variability the performance analysis estimated a structural service life ranging from 1.0 to 5.6 years less, indicating that without the integrated methodology, the project is likely to be undersized. For MRF, the climate change models show that the average rainfall should decrease and years of above-average rainfall will be less frequent. In general, it was observed that the integrated methodology provides gains in the development of infrastructure projects and allows to predict how climate change scenarios may affect these projects.
