The aim of the associated research was determining the effect of the contact pressure and the temperature in the rutting of a closed asphalt mixture, with gradation measured between 0-10 mm, with asphalt CA 60/70, compared with the standardized test at 0,9 Mpa and 60ºC. The research starts with the characterization of the granular material and the asphalt, followed by the determination of the optimal percentage of asphalt by means of the Marshall test and ended with the execution of rutting tests, varying the contact pressure from 0,18 Mpa to 0,9 Mpa, in increments of 0,18 Mpa and the temperature from 40ºC to 70ºC, in increments of 10ºC. The results indicate that there is an effect of the contact pressure and the temperature in the permanent deformation; the above mentioned effect is adjusted to an exponential function in both evaluated variables.
