Los efectos de la forma de la onda de carga en la estimación de la vida a la fatiga de la capa asfáltica en la estructura del pavimento

The phenomenon of fatigue can be considered as one of the main causes of the asphalt Surface course failure. The Four-Point Bending Apparatus is the widespread equipment used to determine the fatigue resistance of asphalt mixtures. Worldwide there are several standard procedures that rule this test. The main difference between them remains in the waveform, in wich the load is applied, and in the failure criteria. This paper reports the influence from the waveform, haversine orsinusoidal, on the fatigue resistance of an asphalt mixture. In adition, through numerical simulation, it was evaluated ones found on sinusoidal tests.
