Impact of Viscoelastic and Fatigue Behavior of Asphalt Mixtures Made with RAP and Asphalt Shingle on the Life Cycle Assessment Results
The use of reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) for the production of new asphalt mixtures has significant effect on their viscoelastic and fatigue properties. Experimental results show that addition of RAP (up to 40%) and asphalt shingle (up to 5%) in asphalt mixtures increased the stiffness and improved the fatigue properties (ε6 parameter). This paper investigates the influence of the viscoelastic and fatigue properties on the environmental performance of a secondary road operated for 20 years over its whole life cycle. Results showed that the use of asphalt mixtures with higher proportion of RAP and RAS had lower global warming potential (GWP), primarily due to the lower use of raw materials and secondarily due to changes to the use phase impacts. Longer road lifecycles and higher levels of road traffic are expected to considerably increase the contribution of the road service phase and in particular that due to pavement deflection at locations experiencing high temperature climates.
