This study evaluates the use of recycled concrete aggregate (RCA) and recycled asphalt pavement (RAP) as an unbound road base. This investigation looked at the climatic behavior (i.e., temperature effects, wet/dry cycling) of RAP and RCA and the effects of brick content on the resilient modulus and plastic strain (as an index) of RCA. The two chapters of this thesis individually discuss each one of these studies. The recycled materials used in this study came from a large geographical area covering eight U.S. states including California, Colorado, Michigan, Minnesota, New Jersey, Ohio, Texas and Wisconsin. Basalt and a quartz/granite/limestone blend meeting Minnesota Department of Transportation’s Class 5 gradation standard were used as control materials.
