| 摘要： | 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: (1) Can the Tollway design, produce, and construct high-quality HMA pavements with high FRAP content mixes; and (2) 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. / Title Note: Summary project rept., 2007-2008. / Supplementary Notes: See also PB2009-106316.
