Definitions

  • This Utility Model applies to a microwave heating equipment for asphalt road repairs, especially for the repairs of potholes or cracks in asphalt roads. Heating of the repaired spots in asphalt roads using this equipment ensures homogeneous joining of the added mixture with the original asphalt surface of the road.
  • asphalt roads are repaired without heating the area around the repaired spot, or with the heating applied immediately before adding the asphalt mixture into the damaged spot in the road, which is more expensive.
  • a water-permeable line forms between the new and the original asphalt surface of the road. This causes yet further damage to the road, starting right in this permeable line. Therefore, the repairs of asphalt roads are more frequently performed with heating applied on the repaired spots, which ensures a significantly higher quality of the repair.
  • the heating is performed either using the devices with gas burners, mostly propane-butane, or more sophisticated equipment that uses infra-red radiation. In both cases, the heat is transferred to the subsurface layer of the repaired spot through penetration.
  • each magnetron with a waveguide is equipped with a fan to cool the magnetron and divert heat from its surroundings.
  • the heat from the surroundings of the magnetron is removed through an adjacent channel to the area of the waveguide.
  • Each set of a magnetron with a waveguide, fan and adjacent heat diversion channel forms an independent integrated heating unit.
  • the required number of units is mounted in a mobile frame, which is equipped with casters. Around the circumference of the bottom of the mobile frame there is a chain screen to prevent the escape of microwave radiation.
  • the heating unit is secured by a system of safety switches, which are connected with the control unit of this equipment.
  • the microwave heating equipment for asphalt road repairs under this Utility Model represents a new and efficient device for heating of the repaired spots, whose integration in the process of repairs of asphalt roads will ensure significant improvement in the quality of repairs and consequently a better durability of the repaired spots.
  • the attached schematic drawing represents a model design of the microwave heating equipment for asphalt road repairs under this Utility Model.
