Resumo
Unpaved roads correspond to approximately 90% of Brazilian’s highway. In most cases they are built without
previous studies should be subject to a many problems. In this work was simulated unpaved roads ditch outlet
spacing, using a software to design roads drainage system. It was used erodibility, critical shear stress and density
values for different soils of roads located in the state of Goias, Brazil. Were simulated different scenarios considering
changes in slope (1%, 5%, 10% and 15%) and in roads channel’s cross section (1:1, 1:2, 1:5 and 1:10). The model
answered favourably to slope and cross section of the channel and to soil resistance parameters. The spacing obtained
indicated that roads with slopes of less than 5%, even high levels of erodibility allowed viable outlet spacing. However,
10% and 15% slopes presented reduced spacing turning them impractical, and so requiring channel protection or
changes of the hydraulics features.
