Damage that occurs in Flexible Pavement is mostly caused by the repetition of the load or trajectory of the vehicle's wheels under extreme conditions. The cause of the damage is due to the strength of flexible pavement which is very dependent on temperature. To overcome the problem of permanent deformation (rutting) due to repetition of load and temperature, the right method is needed to hold the deformation speed. The use of wire mesh layers is thought to be able to overcome this because of the checkered patterns on wiremesh. The purpose of this study is to analyze the velocity of the channel deformation that occurs in the surface layer of a hot asphalt mixture using a wire mesh layer as a reinforcement layer. The study was conducted with an experimental method by making 4 variations of modeling of wire mesh placement on a hot asphalt mixture using a wheel tracking machine. Based on the results of the study, it was found that the hot asphalt mixture with 20 mm wire mesh laying from the surface of the test specimen is the best modeling type with a deformation velocity value of 0.0134 mm/minute and a deformation depth of 2.194 mm. The worst modeling was obtained on a hot asphalt mixture by laying a 30 mm wire mesh from the surface of the test object with a deformation velocity value of 0.0409 mm/minute and a deformation depth of 6.507 mm.
