Blending of Virgin and RAP Binder for Asphalt Mixes with High RAP Contents: A Pilot Study

Creator:

Lewis, Sunny, Coleri, Erdem, Sukhija, Mayank, and Sreedhar, Shashwath

Abstract:

Reusing reclaimed asphalt pavement (RAP) presents an opportunity to reduce environmental burdens and encourage sustainable development. However, a concern exists about blending RAP binder and virgin asphalt binder. While RAP mixtures assume complete blending between these binders, the actual extent of this blending remains uncertain. Lower blending percentages can reduce...

Quantification of Recycled Asphalt Pavement Blending and Tack Coat Performance to Develop Strategies to Improve Pavement Longevity

Creator:

Lewis, Sunny

Abstract:

Decreases in pavement program funding levels have encouraged paving agencies to adopt higher levels of recycled materials into their asphalt mixes. In order to fully evaluate the effects of recycled asphalt pavement (RAP) in Hot Mix Asphalt (HMA) mixes, the level of blending between the RAP and virgin binders in...
