Roads networks, are an integral part of daily trips simultaneously is an infrastructure with large construction costs, which also pollute the environment. This infrastructure, begins wearing immediately after its construction, because of daily use, or environmental conditions or even due to structural failures. The start of this study, referred to concepts such as, asphalt mixtures and asphalt concrete. Then refers to the types of wear and failures to road surface, into four categories: 1) Cracking 2) Surface distortion, 3) Corruption - decay, 4) Surface shining. Also, mentioned the degree of damage severity of the pavement graduated in three levels: 1) Low severity 2) Medium severity 3) High severity. The third part describes the permanent deformation of asphalt mixtures, the basic stages of deterioration and types of surface deformation. The factors of permanent deformation, according to the international references are as follows: A) Aggregates, and in particular the grading curve of the mixture of materials, the geometric shape and proportion of filler materials. B) The type and amount percentage of asphalt. In the fourth part, referred to investigate the international references, which shows how measuring residual surface distortion – deformations as wheel tracking – routing. Also includes References are made to wheel tracking tests at regular asphalt blends or mixtures containing modified asphalt. In the last chapter, describes Pavement Management System, analyzed the structure and data inserted in the database of PMS. The last parameters that analyzed are the prediction models and the index flexible pavements, which provide and evaluate the situation in which the pavement is located from structural and functional part, and under which they can to estimate the pavement maintenance needs.
