Life Cycle Assessment of Greenhouse Gas Emissions from Recycled Asphalt Pavement Production

With the growing impact of climate change, there is an increasing need and obligation to reduce responsible greenhouse gases (GHG) in road construction as well. Using life cycle assessment (LCA) methods, several studies have already separately analysed individual parameters asphalt production process illustrated potential improvements terms GHG reduction. However, data most assessments originate from single sources databases, such can offer little validation against unreliable assumptions. For this reason, addition conducting separate at quarries, batch mixing plants, sites order collect energy material consumption with which calculate emissions, work relies on results multiple found literature. structure for environmental product declarations (EPDs) EN 15804, our are divided into different stages a corresponding modules. This allows systematic comparison products eliminates previous uncertainties regarding inclusion benefits beyond system boundary. The show dominance binder footprint advantage substituting virgin recycled material, well influence moisture emissions process. In evaluating itself, two sections traffic volume (and share electric mobility) were examined compared traffic-related over 30-year lifetime. We confirm that has substantially higher total (>95%); however, its regulation responsibility governments, industry only bring about own sphere seeking further protection.
