BEST PRACTICES FOR INCREASING RAP USESOURCES OF RAPRAP CATEGORIESSTOCKPILING RAPRAP TESTING AND FREQUENCYDetermining Bulk Specific Gravity of the RAP AggregatePLACEMENT OF RAP MIXESCHAPTER 4. CONCLUSIONS AND RECOMMENDATIONSRECOMMENDATIONSACKNOWLEDGEMENTSRecycling asphalt pavement creates a cycle of reusing materials that optimizes the use of natural resources. Reclaimed asphalt pavement (RAP) is a useful alternative to virgin materials because it reduces the need to use virgin aggregate, which is a scarce commodity in some areas of the United States. It also reduces the amount of costly new asphal...

Research trends on thermochromic asphalt mixtures
Asphalt mixtures are commonly used in road pavements, covering a large impermeable area of urban surfaces. They absorb a significant amount of solar radiation, which poses environmental, social, and economic challenges (Golden and Kaloush, 2006, Rosenfeld et al., 1996).This fact exacerbates the formation of urban heat islands (UHIs), among other adverse effects.
