Abstract

carbon dioxide reclaimed asphalt pavement required heat energy Sasobit® warm-mix
Increasing emission of greenhouse gases has worsened the global warming and a great concern to curb this problem from further damage to the environment and living things have captured the attention of many parties. In the asphalt industries, emergence of warm-mix technology has significantly reduced mixing and compaction temperature which consequently lowers the emission from the production process. This paper presents the effects of Sasobit®, one of warm-mix additives, on the required heat energy and CO2 emission on mixing blended binder between pure and aged binder at different proportions of aged asphalt and Sasobit® content. The viscosity-temperature dependency was also investigated which provided fundamental information on temperature control particularly in determination of mixing and compaction temperatures. In this study, asphalt binder grade 80/100 was used and the binder was subjected to long term aging to simulate recovered asphalt binder from reclaimed asphalt pavement. The result shows that addition of Sasobit® in the blended asphalt binders incorporated with aged binder can reduce mixing and compaction temperatures, the required heat energy and CO2 emission.
