- Development of fuzzy models for asphalt pavement performance Sérgio Pacífico Soncim Igor Castro Sá de Oliveira Felipe Brandão Santos Ingeniería Pavements management systems performance models The objective of this paper was to develop fuzzy models for asphalt pavement performance. The fuzzy logic can convert linguistic or qualitative variables into quantitative values. This feature makes it possible to gather experts’ experience about the knowledge they have on factors that affect the pavement performance and its state condition. Forms developed in an organized way were applied for acquiring the knowledge from experts on pavement construction and maintenance. The variables pavement age, traffic, International Roughness Index (IRI) and Flexible Pavement Condition Index (FPCI) were associated with numerical scales and linguistic concepts such as new, old, light, heavy, good, fair, and poor. From the information obtained through the application of forms, variables were modeled with the aid of software InFuzzy and fuzzy models were developed for IRI and FPCI. For validating the model, a straight line adjustment was used to relate the predicted to the observed data. Also, the corresponding correlation coefficient (r) was calculated and residuals were analyzed. The developed models fitted to observed data and correlation coefficient r = 0.71 and 0.70, respectively. 2019 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303260200007 https://www.redalyc.org/journal/3032/303260200007/ https://www.redalyc.org/journal/3032/303260200007/html/ https://www.redalyc.org/journal/3032/303260200007/303260200007.epub https://www.redalyc.org/journal/3032/303260200007/movil https://doi.org/10.4025/actascitechnol.v41i1.35626 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
