    On this research work the structural evaluation of the whitetopping pavement of the Biblián - Zhud track is described thought out of retro calculation techniques. This analysis determines if the results which were gotten by three retro calculation methodologies are related to the results of 18 soil spits, extracted along the way. The structural evaluation is based on the results obtained through non-destructive reflectometry tests through the impact reflectometer (FWD). With these results, the reaction module of the subgrade, the modulus of elasticity and the modulus of rupture of the concrete slab and the efficiency of load transfer between the paving slabs are determined by retro calculation. The methodologies used for the analysis are; AASHTO 93, the Elmod 6 software and finally the critical distance method. Comparing the correlations of the methodologies used for retro calculation, it is determined that, if it is feasible to perform analysis of retro calculation on pavements of whitetopping composite structure, since the results indicate relationships in the range of acceptable and excellent, being the distance method Critical, the one that best fits the field data with a 95% ratio.
