Life cycle assessment of low temperature asphalt mixtures for road pavement surfaces: A comparative analysis

摘要

The increasing fuel consumption demand, the accelerated pressure imposed by the depletion of scarce raw materials and the urgent environmental protection requirements are forcing the change of pavement industry and academia community's research endeavours towards the development of low emissions road paving technologies able to significantly reduce mixing and compaction temperature as well as the consumption of virgin raw materials. One of the relatively recent technologies in the field of pavement materials that aims at addressing those concerns is the incorporation of reclaimed asphalt pavement (RAP) in the production of warm mix asphalt (WMA).
