• Abstract:
  To test the fractionated recycled asphalt pavement (FRAP) materials, the Illinois Tollway, working through its ; contractors and consultants, developed and conducted a project on the applicability and feasibility of using ; increased RAP contents through FRAP. The goal of the program was to answer two main questions: ; • Can the Tollway design, produce, and construct high-quality HMA pavements with high FRAP content ; mixes? ; • Will these materials provide the same or better pavement performance as the standard mixes used by ; the Tollway and Illinois Department of Transportation (IDOT), and with performance that is consistent ; with pavement design procedures? ; In the summer of 2007, a construction contract was awarded for advance pavement work on the Jane Addams ; Memorial Tollway (I-90) in the Rockford area. The timing, scope, and circumstances of the I-90 project provided ; a rare opportunity to evaluate several different HMA concepts directly via plant mixing and field trials. This is a ; summary report of the field trial production mixes containing high quantities of FRAP sponsored by the Illinois ; Tollway. ; The results of these field trials show that the Tollway can design, produce, and construct high-quality HMA ; pavements with high FRAP content mixes. Further, the laboratory evaluation of these mixes shows that their ; performance is expected to be similar to currently used materials and consistent with current pavement design ; procedures. The issue of asphalt cement grade bumping was evaluated with the field trials and, based on these ; results, there is no need to double bump the asphalt cement grade within the design criteria.
