Abstract:Reclaimed or recycled asphalt pavement (RAP)
and recycled asphalt shingles (RAS) have been
widely used in hot-mix asphalt (HMA) in Texas.
However, a high volume of RAP is still available
in stockpiles along the Texas Department of
Transportation’s (TxDOT’s) highways or at HMA
concrete producers’ plants, in spite of their use
by the asphalt industries. Ground RAS from
manufacturers and post-consumer uses are also
available. The possible use of RAP and RAS in
portland cement concrete (PCC) would not only
help dispose of excess RAP and RAS, but also
provide a cost reduction for aggregates in
hydraulic cement concrete.
