Se muestra  el  comportamiento  de  las  variables  de
las  leyes de  fatiga, deformación y deflexión de una
estructura de pavimento flexible. Para el análisis se
adoptó una estructura  típica de pavimento  flexible,
revisada  por  el método  racional,  de manera  que
cumpla  con  los  criterios  de  fatiga,  deformación  y
deflexión.  Las  leyes  de  comportamiento  utilizadas
para el análisis fueron las siguientes: la ley de Fatiga
de  la mezcla asfáltica, deducida por  la Shell,  la  ley
de  deformación  de  la  subrasante,  deducida  por  la
Shell para los niveles de confianza del 50%, 85% y
95%,  la ley de esfuerzos sobre la subrasante, deducida
por Dormon-Kerhoven y la CRR de Bélgica, y la ley
de deflexión utilizada, deducida por Yang Huang.
Como  resultado  del  análisis  se  obtuvo  el  grado  de
sensibilidad de cada una de las variables que integran
las  leyes  de  fatiga,  deformación  y  deflexión  y  la
