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. The current state of the practice is based on the assumption that complete blending occurs between the RAP and virgin binder. The 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.
