Department of TransportationBerry, MichaelDalton, KelseyMurray, FlynnWestern Transportation InstituteUS Transportation CollectionEach year, the US highway industry produces over 100 million tons of reclaimed asphalt pavement (RAP) through standard rehabilitation and construction of the nation\u2019s roads. Although this product has been reused in several applications, usually in hot plant mixes, a large portion of this material remains unused. With a sizeable share of RAP wasted in stockpiles and landfills, the exploration of further uses for this construction byproduct is warranted. Using RAP as aggregate in Portland cement concrete pavement (PCCP) is one possible application for this recyclable material. Portions of virgin aggregate used to produce concrete pavement may be replaced with RAP, creating a pavement that is both efficient and environmentally friendly.90
