RESUMO

In this research is accomplished a comparative study between three empirical processes of flexible pavements design, alI, with conceptual bases substantiated by the CBR method.The processes of the Corps of Engineers (1962), the AASHTO (1972) and the DNER (1966) are compared, with the objective to analyze the trend of behavior of these last, in relation to the two first mentioned. Primarily, will be studied the methodologies of each one processes and, hereafter, they will be submitted to a comparison between themselves. This comparison will have as comment parameter, the obtained thicknesses of pavements for each process, when submitted to the compositions of equal traffics and to the same subgrade conditions. With this comparison will be evidenced, which the methodologics influences that really occur in DNER process, by the Corps of Engineers and the AASHTO processes. Thus, will be pointed out the aspects that can be disconsiderated in the methodology adopted for the DNER, to flexible pavements design, in order to adjust it to the brazilian conditions with scientific endorse, however without compromising, the validity of its results. ...Note: The complete abstract is available with the full electronic digital thesis or dissertations
