PROBLEM TO BE SOLVED: To provide a method and device for the cooling management of a coarse aggregate capable of bringing the coarse aggregate into a sufficiently usable state by cooling it to 18-22°C even in summer.;SOLUTION: In an aggregate storage facility with a plurality of aggregate bottles 1 arranged in parallel for storing and discharging the fine and coarse aggregate at each particle size group, three aggregate bottles 1(1a, 1b, 1c) are prepared at each particle size group to store and discharge the coarse aggregate, and an operation is repeated by a one-day time lag to the three aggregate bottles 1a, 1b, 1c thereby one bottle per day of each coarse aggregate classified in each particle size group is cooled to be usable. The operation is composed of two-day processing work which cools the coarse aggregate to a temperature of 18-22°C by filling a one-day use amount of the coarse aggregate to an empty aggregate bottle and sprinkling cooling water to the aggregate and suspending the sprinkling of water to drain the aggregate. A process on a third day to discharge the coarse aggregate from the aggregate bottle is repeated.;COPYRIGHT: (C)2011,JPO&INPIT
