Federal Highway AdministrationTexas. Dept. of Transportation. Research and Technology Implementation OfficeUS Transportation CollectionReclaimed or recycled asphalt pavement (RAP)and recycled asphalt shingles (RAS) have beenwidely used in hot-mix asphalt (HMA) in Texas.However, a high volume of RAP is still availablein stockpiles along the Texas Department ofTransportation\ue2\u20ac\u2122s (TxDOT\ue2\u20ac\u2122s) highways or at HMAconcrete producers\ue2\u20ac\u2122 plants, in spite of their useby the asphalt industries. Ground RAS frommanufacturers and post-consumer uses are alsoavailable. The possible use of RAP and RAS inportland cement concrete (PCC) would not onlyhelp dispose of excess RAP and RAS, but alsoprovide a cost reduction for aggregates inhydraulic cement concrete
