Application of solar aggregate stockpiles in the process of storing recycled materials

This paper presents the potential applications of solar aggregate stockpiles intended for storing materials used in the production of hot mix asphalt. The stored materials are crushed stone, waste glass and recycled asphalt. Three set-ups i.e. models of solar stockpiles were made for testing, each having an equal volume, form, type and thickness of thermal insulation, and size of the opening through which sunlight is acting. The research aimed at determining the effects of exposure to sunlight on the temperature of the stored materials, the growth/loss of material temperature, the effects of different types of stored materials on the mixture temperature, and temperature loss in periods where there was no exposure to sunlight. The conclusions drawn from the analysis are that temperature stored in the stockpile material is affected by the duration of its exposure to the sunlight, the type of material stored, the way it is stored, and when it is stored.
