“…Solar stockpiles were shown in previous research where the mineral mixture is stored for use in the manufacture of HMA. These solar stockpiles are designed for the primary goal of achieving the maximum temperature of the aggregate stockpile during its exposure to the sunlight and minimising its loss during periods without exposure to the sunlight.…”
Summary
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, ie, 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.

“…Thus, McDonald [4] considers in his paper possible use of plastics, incinerator ash, waste tyres, shingles, fly ash, slag, cement dust, recycled asphalt, glass, etc., in asphalt mixtures. In this respect, some authors [5][6][7][8][9] study possible use of recycled asphalt in the production of new asphalt mixtures, in the production of waste plastics [10][11][12][13], in the production of waste glass [14][15], and in the production of fly ash [16][17] etc. The use of alternative materials in the production of asphalt mixtures generally leads to economic savings and smaller negative environmental effects, while also being compliant with relevant quality requirements.…”
An overview of research conducted so far on the use of various recycled materials as replacement for stone filler in asphalt mixes is presented in the paper. The paper comprises an overview of research on the influence exerted by the waste glass, waste materials from cement industry, concrete, brick, ceramics, fly ash and other materials, on physicomechanical properties of bitumen mixes. As a final result, conclusions are given on the possible use of individual recycled materials as replacements for standard rock flour in asphalt mixes. Utjecaj recikliranog punila na svojstva asfaltnih mješavina U radu se daje prikaz provedenih dosadašnjih istraživanja s primjenom različitih recikliranih materijala koji se koriste kao zamjena za kameno punilo u asfaltnim mješavinama. Rad obuhvaća prikaz provedenih istraživanja o utjecaju otpadnog stakla, otpada cementne industrije, betona, opeke, keramike, letećeg pepela i drugih na fizikalno mehanička svojstva bitumenskih mješavina. Kao konačan rezultat donose se zaključci o mogućoj primjeni pojedinih recikliranih materijala kao zamjeni za standardno kameno brašno u asfaltnim mješavinama.
