Resumen:
Studies accomplished in Brazil and in the exterior studding comes the importance of the models of acting forecast in the implantation of systems of management of pavements or even, in the activities of rehabilitation of pavements. This work has the objective of developing models of acting forecast for the highways of the state of Paraíba. For so much the data of surfaçe evaluations were used and it structures, accomplished among the
years from 1990 to 1993 by the technical team of the DER-PB in 24 highways. These evaluations had included analysis space, being evaluated each highway in just one year that allowed to use the methodology developed by Shain & other (1987). Soon after they
assembled several highways, in function of its climatological and geographical characteristics of the area and type coating of the highways, what allowed the formation five groups of highways. They were correlated, for each group, the data of surface evaluation (IGG) and the data of structure evaluation (of the and I Stripe) with the age and the traffic of each highway resulting in an acting tendency for each group and each correlation. Hewever it was only obtained satisfactory results in the correlation' s with
the age because it was not had a historical study of traffic of the analyzed highways, being necessary to reach the wanted objective, to work with having given not select. With base in the preliminary analyses and in the final results it could be concluded that the analyzed highways don1t find on the other hand in good state under the superficial aspect they present a good state with relationship to the structural aspect. Finally, this research exhibition the importance of the models of acting forecast, which permitted to analyze the behavior of the pavements evaluated along its useful life.
