El desempeño al ahuellamiento(a) de mezclas asfálticas se evalúa en laboratorio a través del ensayo de pista. Las condiciones de carga y temperatura a las que se lleva a cabo son en general extremas para poner de manifiesto el problema. Diferentes ensayos utilizan diferentes temperaturas y cargas con límites de desempeño asociados a ellas. Sin embargo estos no tienen en cuenta la variación de temperatura o carga. En este trabajo se estudió el desempeño(b) de una mezcla elaborada con tres asfaltos(c) en el equipo de pista a temperaturas de 50, 60 y 70 °C. Se relacionaron los resultados para cada ligante obteniendo una relación entre el ahuellamiento y la temperatura y se proponen factores de corrección de un límite en función de la temperatura.
Laboratory wheel tracking test is used to evaluate the Asphalt mixture rutting performance. The temperature and load test condition are extreme to manifest the problem. Different wheel tracking tets used different temperature and loads with performance limits associated with them. However temperature and load variation are not take into account. In this work the performance of one asphalt mixture elaborated with three different asphalts binders was studied in the wheel tracking test at 50, 60 and 70 °C. The different binder’s performance results against tempereture were related and it is proposing temperature correction factors for one rutting limit.
