Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   Conduct binder and mix testing to evaluate blending of reclaimed asphalt pavement (RAP) and virgin binder.
Goals:   The key project objective is to better understand blending of reclaimed asphalt pavement (RAP)/virgin asphalt binders.┬áThe current state of the practice is based on the assumption that complete blending occurs between the RAP and virgin binder.┬áThe hypothesis of this study is that complete blending does not occur; however, complete blending may not be necessary for proper performance in asphalt mixtures.
Product Type:   Data
Research report
White paper
Test Methodology:   Hypothesis, experimental design and plan, test methods, and analysis of results.
Expected Benefits:   Improved understanding of how reclaimed asphalt pavement (RAP) behaves in asphalt mixtures and identification of research needs for properly evaluating high RAP mixtures.
Deliverables: Name: Technical/research report and publication.
Product Type(s): Research report, Data, White paper
Description: The deliverables are a white paper explaining the research approach, presentation for information transfer, and a publication.
