Life Cycle Assessment of Asphalt Mix Containing Jordanian Oil Shale Ash

Abstract

The focal theme of this study is to evaluate the life cycle of asphalt mix containing Jordanian oil shale ash (OSA). Life cycle assessment (LCA) approach was conducted to assess the environmental impact of all manufacturing stages of the asphalt mix from Global Warming Potential (GWP) and Energy Consumption (EC) perspectives. The documentation for the LCA study was done in accordance with ISO 14044:2006 standards for the research's goal and scope, inventory analysis, impact assessment, and interpretation. The results revealed that replacing the asphalt mix partially with Jordanian OSA (10 wt.%) resulted in slight reduction in both GWP and EC. A reduction of 2.83% and 4.8% for GWP and EC, respectively, was obtained.
