Patent abstract
Thermal processing of recycled asphalt pavement (RAP), having up to approximately 8% or more moisture content, dries and preheats the material to enhance efficient recycling in a hot mix asphalt plant. A combustor and heat exchanger reheat circulating hot oil, which with hot gas, moves through a hollow auger and around the RAP counter to the flow of RAP. Moisture is forced outward from within the particles and is flashed away by the hot exhaust gas. A similar secondary heater heats the RAP to just below asphalt coking temperature before the hot dry RAP is added as an aggregate to the hot mix asphalt plant.
