• Abstract:
  Over 90 percent of ; U.S. roads are paved ; with asphalt, which ; must be periodically ; resurfaced. Milling ; produces reclaimed ; asphalt pavement (RAP), ; which can be recycled ; in hot-mix asphalt, ; but at no more than ; 25%. Therefore, much ; RAP remains for other ; roadway applications. ; RAP is a well-drained, ; granular material available on site; however, 100% ; RAP has low bearing strength and creeps under ; load. ; In this project, Florida Institute of Technology ; researchers sought to improve RAP bearing ; strength and reduce creep to levels acceptable ; for roadway base applications. Several processing ; methods and additives were tested. Specimens ; were evaluated wet and dry by strength tests, ; including limerock bearing ratio (LBR), unconfined ; compression, Marshall compression, and indirect ; tensile tests. Seven-day, one-dimensional ; consolidation tests evaluated creep deformation.
