“…Although RHA has been widely used in many work area, there are only few studies about the use of RHA in the asphalt concrete mixtures. In a recent study, Sargın et al [36] investigated the usability of RHA in HMA concrete as mineral filler. They found that 50% RHA and 50% LS of filler rate mixtures had the best Marshall stability.…”

“…are being utilized as alternative to conventional fillers (Sharma et al 2010;Das and Swamy 2014;Huang et al 2009;Karasahin and Terzi 2007;Kuity et al 2014;Mills-Beale and You 2010;Sargin et al 2013;Taha et al 2002;Xue et al 2009). Given that the specific gravity values of some of these alternative fillers may significantly be different than the conventional ones, use of weight proportioning may result in application of undesirably low or high quantity of filler in the mix.…”

The type and quantity of filler influences the property of the asphalt mix. The filler quantity, similar to fine and coarser aggregates, is typically specified in proportions of weight. If the specific gravity of the filler is significantly different than the rest of the aggregates (for example, alternative fillers derived from industrial and domestic wastes), weight proportioning may lead to undesirably low or high quantity of filler in the mix. To investigate this issue further, in the present work filler concentration (in terms of percentage area occupancy) is studied at the microscopic level with the help of a scanning electron microscope. Three different types of fillers are chosen and are separately added to asphalt mix in varying proportions. The indirect tensile strength values and the corresponding filler concentration levels of these samples are noted. From limited data gathered in the present study, it appears that the average filler concentration values corresponding to the maximum indirect tensile strength levels for the mixes are statistically same. That means, even though optimum filler quantities (by weight) are different for these three mixes, the filler concentration values are almost the same. Subsequently, design chart is suggested to estimate the optimum quantity (by weight) of filler for asphalt mix for any given type of filler.

“…Electrical conductivity of mixture with coal dust is higher compared to the control mixture, which makes this waste material suitable for use in asphalt mixtures for thermoelectric asphalt courses that enable faster melting of snow. Sargın et al [48] studied the possibility of using rice husk ashes as filler for asphalt mixes. Four mixtures with 4, 5, 6 and 7 % of filler by weight were designed with an optimum proportion of bitumen.…”

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.
