<p>An aggregate heating apparatus (20) is provided with: a first heating furnace unit (54), which heats an aggregate (12); a second heating furnace unit (52), which is provided below the first heating furnace in the vertical direction, and which heats the aggregate by means of a heat source (62) that uses electricity, said aggregate having been heated by the first heating furnace unit; and a first heat supply path (102), which supplies the first heating furnace unit with heat generated in the second heating furnace due to the heat source. The first heating furnace unit heats a material in the first heating furnace unit using the heat supplied through the first heat supply path. Consequently, the aggregate heating apparatus (20) and an aggregate heating method, whereby load on the environment can be reduced, are provided.</p> |
