Rutting performance (a) of asphalt mixtures is evaluated through laboratory test track. Load conditions and temperature at which it is carried out are generally extreme to highlight the problem. Different trials using different temperatures and loads associated with them limits performance. However these do not consider the variation of temperature or load.

In this paper the performance (b) a mixture made with three asphalts (c) on the track team at temperatures 50, 60 and 70 ° C was studied. the results for each binder were related obtaining a relationship between the temperature rutting and correction factors and a limit depending on the temperature are proposed.
