    This data publication contains the data related to the scientific contribution "Investigating end-of-life allocation approaches for bituminous mixtures" by Haverkamp et al. (2025) Abstract of the corresponding paper: This study examines end-of-life (EoL) allocation in Life Cycle Assessment (LCA) of bituminous mixtures, comparing four: 0:100 (EoL burdens and credits attributed to secondary material producer), EN 15804 (burden split at end-of-waste), 50:50 (burdens and credits divided equally), and Circular Footprint Formula (CFF) (allocation considering market situation). Notably, this is the first application of the CFF to bituminous mixtures. Each method is evaluated regarding recyclability, downcycling avoidance, applicability to bituminous mixtures, and loop considerations. In the case study, the 0:100 method yielded the lowest Climate Change impact (-10.7 kg CO2 eq./t), followed by EN 15804, 50:50, and CFF (65.1 kg CO2 eq./t). While 0:100 and 50:50 were the most straightforward approaches, EN 15804 and CFF were more sensitive to market conditions. Sensitivity analyses covering reclaimed asphalt content, binder availability, quality ratio, and EoL fate highlighted the importance of selecting appropriate allocation methods to ensure accurate results and support circular economy strategies.
