The main objective of the study was to conduct a LCA of Asphalt Rubber-Gap graded (AR-Gap) pavements and compare the environmental impacts of AR-Gap pavements with the conventional pavement. The scope of the study included the determination of Greenhouse Gas (GHG) emissions during the various stages of pavement construction, including raw material production, mixing, transportation, placing, and compaction. For this study, AR-Gap and conventional pavements are designed as per IRC:37-2018 guidelines using IITPAVE for three subgrade and three traffic conditions, totalling nine design combinations. The material quantities were calculated for all design combinations and respective GHG emissions were determined. The comparative analysis of the GHG emissions from AR-Gap and conventional pavements showcased that AR-Gap pavements produced lower level of emissions in comparison with the conventional pavement. Overall, it is anticipated that this study will provide a background on the life cycle analysis of AR-Gap pavements and their GHG emissions during the various stages of pavement construction. It is envisioned that this research study will set a strong venue for advancing the current state of the art pertaining to AR-Gap pavements and consideration of the same as a sustainable pavement alternative to conventional asphalt concrete pavements.
