Resumen
The purpose of this paper is to present an experimental study to characterize the mechanical behaviour of warm mix asphalt (WMA) mixtures designed with Chilean natural zeolite and different amounts of reclaimed asphalt pavement (RAP) for sustainable pavement construction. Five WMA mixtures were evaluated and compared with one reference hot mix asphalt (HMA). Two WMA mixtures were fabricated with 0.3% and 0.6% w/a natural zeolite, and three WMA mixtures were fabricated with 0.6% w/a natural zeolite and 10%, 20% and 30% RAP content. The binder contents and volumetric properties were obtained according to Chilean standards. The mechanical properties evaluated were stiffness modulus, cracking resistance, moisture sensitivity, resistance to rutting and fatigue behaviour. The results showed that WMA mixtures with natural zeolite can be manufactured at a temperature of 20 degrees C lower than reference HMA, fulfilling the design specifications. Likewise, recycled asphalt mixtures can be fabricated at a lower temperature using natural zeolite, showing good performance properties to be used for sustainable pavement construction.
