Optimizing the Highway Lifetime by Improving the Self Healing Capacity of Asphalt
2012 (English)In: Transport Research Arena 2012, 2012, Vol. 48, 2190-2200 p.Conference paper (Refereed)
It is of imminent urgency to optimize the lifetime of asphalt binders from the remaining available crude sources. This paper presents a recently developed model in which the self-healing capacity of bitumen is based on fundamental chemo-mechanical parameters. The implications of the enhanced bitumen healing rates are investigated by utilizing a newly developed Open Life Cycle Assessment framework. From the case study it was concluded that using bitumen with self-healing capacity can lead to a significant reduction in Greenhouse Gas emission and energy usage. Additionally, the importance of knowing the fuels and emission of bitumen modifiers on the highway sustainability was demonstrated.
