Resumen
Studies carried out over time indicate that in most cases the structure of a road is designed
for a useful life of no less than 20 years; however, it is known that pavements provide
adequate service conditions for only between 8 and 12 years due to pavement deterioration.
This research work seeks to analyze and evaluate the existing deterioration models for
asphalt pavements, in order to assess the parameters involved in the deterioration behavior.
To analyze the different deterioration models considered in this research, MATLAB
computational tool will be used, here models will be programmed and the parameters will
be varied according to each type of deterioration and the results will be obtained in a graphic
form. From the results obtained, it was observed that the parameters age of the pavement
and the traffic are directly proportional to the beginning or progression of most of the model
deteriorations. Also from the analysis of other parameters, it was found that the use of binder
content above the optimal content in bituminous surfaces helps certain deteriorations in
asphalt pavements to occur with less severity or in less time. From the study carried out, the
importance of the analysis of the deterioration models is concluded, since it has allowed
defining the most critical parameters for the types of deterioration analyzed according to
their deterioration model.
