Project Title:
  Determination of Usable Residual Asphalt Binder in RAP
Start Date: 7/1/2006
End Date: 6/30/2008
Summary of Project:
  The state of Illinois has been using reclaimed asphalt pavement (RAP) in hot-mix asphalt (HMA) pavements since 1980, but the optimal design of these pavements has been continually questioned. Therefore, ICT is working to improve the design of pavements with RAP and investigate the use of RAP with up to 50% of the total original material. This research focuses on understanding the interaction between the new and recycled asphalt components using state-of-the-art technologies, including nanotechnology and scanning electron microscopy, to quantify the effectiveness of using RAP in HMA Developing a better design for pavements that use recycled materials results in significant environmental benefits and cost savings.
Objective of Project:
  To study the significance of residual asphalt binder in Reclaimed Asphalt Pavement (RAP)that is used in hot mix asphalt.
Expected Outcome:
  The project outcome is a scientifically proven approach to optimize the use of RAP in new pavements.
