“…As a result, that asphalt concrete demonstrated high physical and mechanical properties, such as thermal and water resistance. The further experience in using the fly ash waste is also presented in [7][8][9]. The results of other studies [1,2,10] demonstrated that adding the fly ash into the composites increased the bitumen consumption because of the lower structuring in comparison with pure carbonate powders.…”

-The industrial powder waste from thermal power plants such as fly ash is used as asphalt or mineral filler due to its properties and dispersibility. However, the conflicting data on the fly ash usage are due to the different compositions, dispersibility, reaction capacity of the used fly ash. This paper presents the detailed research of the structuring process in bitumen-mineral compositions experimentally studied under the water saturation tests. The water saturation for the asphalt cements evaluates the strength of adhesion of the binder film to the particle surface as well as the stability of the bitumen-mineral structure when saturating water under the reduced pressure and elevated temperature. Depending on the fly ash composition, the structure formation operates differently at the component cohesion stage and during the swelling test. In bitumen-mineral composites, based on the high-lime ash, the mineral hydration leads to the binder film liftoff as well as to the change of the ash phase composition due to the low adhesion of bitumen and mineral particles. That results in undesirable formations in the system such as calcium sulfate dihydrate and ettringite, particularly. These formations cause the structural softening and the swelling of asphalt cements. The higher bitumen -low-lime ash adhesion provided the more stable structure of asphalt cements under testing. That resulted just in the binder film deformation without its liftoff. The swelling of the bitumen compositions was provided by the low packing density of ash particles in the asphalt cement.Keywords-the thermal power plant fly ash, swelling test; asphalt cement; structure formation; new formation.

“…A study made by Suheibani [6] revealed that addition of class F fly ash in bituminous concrete provides superior indirect tensile strength, rut resistance, and fatigue life. Following micro structural investigations of asphalt binders modified with fly ash, Sobolev et al [7] concluded that the crack -arresting behaviour effect was successfully induced by fly ash particles evenly distributed in bitumen matrix. The research confirmed feasibility of using fly ash to improve the properties and performance of asphalt binders and mixtures.…”

Effect of fly-ash based geopolymer coated aggregate on bituminous mixturesThe research presented in the paper is conducted to evaluate properties of fly ashbased geopolymer coated aggregates and their effect on characteristics of bituminous mixtures. The investigation included aggregate testing, scanning electron microscope (SEM) analysis of fly ash and fly ash-based geopolymer, Marshall mix design, indirect tension test, dynamic shear rheometer (DSR) test for rheology, and repeated load test on bituminous mixtures with fly ash-based geopolymer coated aggregates. Istraživanje prikazano u radu provedeno je u svrhu određivanja svojstava agregata obloženog geopolimerom na bazi letećeg pepela i utjecaja tih svojstava na karakteristike bitumenskih mješavina. Provedeno je ispitivanje agregata, analiza letećeg pepela i geopolimera na bazi letećeg pepela mikroskopom za elektronsko skeniranje (SEM), ispitivanje mješavina Marshallovom metodom, indirektno vlačno ispitivanje, ispitivanje reologije reometrom s dinamičkim smicanjem (DSR) te ispitivanje bitumenskih mješavina s agregatom obloženim geopolimerom na bazi letećeg pepela opetovanim opterećenjem.Ključne riječi: geopolimer na bazi letećeg pepela, obloženi agregat, bitumenske mješavine, mikroskop za elektronsko skeniranje Vorherige Mitteilung
