In a rational design of flexible pavements, the response before loading is given in terms of stress, deformations and deflections in each of the forming pavement layers Selvaraja, 2012 Response models are mainly based on the multilayer elastic theory on which several computer programs have developed Alize III, Kenpav, Depav, Cedem, Bisar, etc Such programs have become an essential tool in determining stress and deformations in the pavement structure Zheng et al., 2012;.
Los modelos de respuesta están basados principalmente en la teoría elástica multicapa, sobre la cual se han desarrollado varias aplicaciones de computador Alize lll, Kenpav, Depav, Cedem, Bisar, etc que se han convertido en una herramienta fundamental para determinar los esfuerzos y deformaciones actuantes en la estructuras de pavimento Zheng et al., 2012; Quintana y Lizcano, 2007.
