N2 - The continuous increase in the number of heavy vehicles usually causes the wearing course to present greater permanent deformation in less time, due to its low resistance to traffic loads. Given this, several studies carried out in the laboratory have tried to reduce the permanent deformation using additives such as glass fiber. That is why this work analyses the effect of glass fiber on the permanent deformation of wearing courses using ANSYS. First, the mechanical properties of asphalt mixtures with different percentages of glass fiber were compiled in order to create materials that represent each mixture in ANSYS. Then, the simulation of the Marshall stability and flow test was carried out to configure the materials created. Finally, materials were evaluated in the wearing course model created and the permanent deformation associated with each one of them was obtained. The results showed that glass fiber reduces the permanent deformation of the wearing course by an average of 15%, unlike mixtures without fibers. In addition, it was concluded that the ideal fiber content that could be used to improve the resistance of wearing courses to permanent deformation is between 0.25% - 0.40% glass fiber.
