Experimental study on usability of various construction wastes as fine aggregate in asphalt mixture

In this study, some properties of asphalt mixture containing ceramic, marble and redbrick as recycled waste materials were investigated. Because of the low strength, recycled waste materials were used only as fine aggregate and filler. Various tests including moisture susceptibility, Marshall stability, Cantabro, mechanical composition, mineral composition and physical properties test were conducted. In addition, softening point and penetration properties of asphalt mastic containing the above-recycled waste materials as powder were researched. The results indicated marble mixture exhibited better performance than other mixtures, especially in 25% content. In addition, from asphalt mastic test results, ceramic asphalt mastic showed the superiority of high and low-temperature properties.
