Hot in-place recycling of asphalt pavement by a method which utilizes microwave energy in combination with hot-engine exhaust gases has been demonstrated to be technically and economically feasible. The process saves both energy and materials compared with conventional hot-mix recycling methods involving removal of old paving and reprocessing at hot-mix plants. Applications for microwave pavement heating include repair of cracks, joints between lanes and shoulders, wheel tracks, bridge decks, strip patching, and eventually in-place recycling of full lanes of asphalt highways. The ability of microwave energy to heat pavements rapidly and fairly uniformly to depths of up to 6 inches make this new method uniquely suitable for repair and restoration of bridges, roads and highways, and also for the construction of new paved roads in places where hot-mix plants are not available.
