Abstract (en)
A microwave heating equipment for asphalt road repairs, containing two microwave heating units (11), which are located in a mobile frame (7). The heat source of each heating unit (11) is a magnetron (1), which generates microwave radiation at the frequency of 2.45 GHz. Next to the magnetron (1), there is a waveguide (2) designed to guide and aim the microwave radiation from the magnetron (1) to the repaired spot on the road (10). Further, the heating unit (11) contains a fan (3) to cool the magnetron (1) and to divert the heat from its surroundings towards the waveguide (2). The mobile frame (7) is equipped with casters (9) and a chain screen (8) to prevent the escape of microwave radiation. The source of energy can be the electricity supplied by the ordinary means (230/400 V) or by a mobile power unit.
