In this research effort, a methodology is proposed to project the performance of flexible pavement in terms of roughness through the IRI, it was based on deterioration prediction models developed by the HDM-4 program from the failure mechanism of asphalt pavement and Markovian methods through Markov chains, allowing to incorporate the probabilistic behavior of the pavement in the prediction of its condition to guarantee that it actually occurs during its useful life; becoming a powerful and sophisticated tool for pavement management systems, supporting in an engineering way the decision making process of maintenance and rehabilitation of roads in a viable way to achieve adequate service levels and optimizing the available resources. This process begins with the collection of field data with nondestructive testing of IRI and deflections using the Laser Profilometer equipment and the FWD Impact Deflectometer and information on soils, traffic and climate, likewise, from the deflectometry, the elastic module and the adjusted structural number of the pavement are calculated; allowing to elaborate a database to implement the deterioration models of cracking, rutting and roughness during the years collected from the IRI; these pavement roughness results will be statistically discriminated by data filtering and outlier detection to eliminate defective data, having representative measurements to be used in the modeling with homogeneous and non-homogeneous Markov Chains, using different Markovian methods such as absolute distance, site condition, data regression, data distribution, and percentage and implementation of Monte Carlo simulation with Markov Chains; in order to be evaluated and obtain the efficient performance model to project the pavement roughness by means of its deterioration curve during a given time.
