This thesis proposes a structural model to determine the remaining life of flexible pavement with a mechanistic approach that models rutting and cracking failures alligator are used. For this purpose it uses a data base average monthly temperature and maximum deflections proposed by the environmental area and type of pavement. The deflections are determined on field with Falling Weight Deflectometer (FWD) which are corrected by temperature and are projected for each month of the year according to database averages. For each deflection monthly is calculate the deformations of comprehension on top of the subgrade (ec) and tension at the bottom of the asphalt (et) where models are used rutting and cracking respectively determining the number of loads that produce failures. With the estimate of the expected number of loads ESAL designs, it is possible to determine what percentage of the life is used each month by the law of Minner. Different failure levels for rutting and cracking are set based on the importance of the pavement. The number of months to failures is also adjusted by the existing levels of rutting and cracking on the section at the time the FWD testing. The proposed model is an alternative and simple tool in the management of pavements, where we show the injury analysis Monthly pavement over the years of service or design ESAL.
