RESUMO

A backcalculation procedure for flexible pavements is introduced based on inertial point theory for subgrade backcalculation readapted to theoretical deflection basins obtained with the load to Benkelman beam test. Beside subgrade backcalculation, it was developed a factorial mathematical model to obtain equivalent resilient modulus from the layers presents upon subgrade, considered as unique and denominated equivalent layer. To the readaptation of inertial point theory and preparing of factorial model were used theoretical deflection bowls data base generated by ELSYM5 program. The subgrade and equivalent layer modulus backcalculation were evaluated to the proposed process through others similar backcalculation methodologies. The inertial point theory provides the development of simple algorithms, convergent and with unique solution for flexible pavements subgrade backcalculation minimizing the influence of engineer experience in the problem answer. The backcalculation procedure developed in this research is characterized by simplicity being of suitable use at network evaluation level among others.
