Title: Microwave methods enable energy savings in restoration of highway pavements

OSTI ID:5274734

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 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.
