Implementación del espectro de curvas de diseño ramcodes de suelos no saturados de subrasantes en el diseño de pavimentos flexibles

The design process for a pavement structure assumes that the subgrade will saturate at some point during service life, however, saturation of depends on conditions depending region in which it is located. Therefore, necessary to study partially saturated subgrade. present research aims implement spectrum RAMCODES curves unsaturated soils, applied flexible pavements under environmental and traffic associated with Oyon-Ambo highway. To construct curves, CBR tests were performed by varying compaction energies moisture contents. Likewise, using OriginPro 2019 program, obtained mathematical model was used predict variation degree over time. Subsequently, seasonal correlated obtain resilient moduli. Finally, two designs carried out, one traditional characterization methodology other according proposed methodology. From results obtained, interpreted consideration behavior optimizes since bearing capacity increased 28.8%, means thickness subbase layer reduced 25%.
