Using reclaimed asphalt pavement (RAP) has grown significantly since the oil embargo of the 1970s. The National Asphalt Pavement Association reported that over 71 million tons of RAP were used in 2014 (NAPA 2015). RAP was traditionally used in warm-mix asphalt (WMA) and hot-mix asphalt (HMA) construction, including conventional and thin HMA overlays, but there...

The Kentucky Transportation Cabinet (KYTC) maintains over two hundred steel bridges constructed with types of steel which are unknown. Kentucky Transportation Center (KTC) researchers have developed a procedure for determining steel tensile properties (0.2% yield strength and ultimate tensile strength) which can be used to help identify unknown steels. The...
