Title:
ASPHALT FINISHER
Document Type and Number:
WIPO Patent Application WO/2016/042927
Kind Code:
A1
Abstract:
The present invention heats an asphalt mixture loading part uniformly to a high temperature in a short time, compared to prior art. An inner steel plate 11, an outer steel plate 12, an electric heating sheet 13, a heat insulating sheet 14, and a convection layer 15 form a heating device 10 which heats an asphalt mixture loading part 3. A hopper 6 or the like has a double-plate structure. Between the inner steel plate 11 and the outer steel plate 12, a space extending along the steel plate surfaces is formed. The electric heating sheet 13 is in close contact with the inner side of the inner steel plate 11. The heat insulating sheet 14 is in close contact with the inner side of the outer steel plate 12. Between the electric heating sheet 13 and the heat insulating sheet 14, the convection layer 15 is formed.
