“…In some EU countries the proportion of recycling has reached as much as 60 %, which is much more compared to situation in the Republic of Croatia where 33,747 tons of waste glass was collected and classified in 2012 [24]. Hand-crushed waste glass used as replacement for a part of filler in the testing is shown in Figure 2 [25]. In the study conducted by Hassan et al [26], glass powder is used as an alternative for mineral filler (stone dust) in the hot asphalt mixture.…”

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.

“…Ghasemi and Marandi [22] studied the efficiency of bitumen and asphalt mixtures modified with crumb rubber and recycled glass powder, concluding that using recycled glass powder (RGP) instead of crumb rubber (CR) has no negative impact on the efficiency of bitumen and asphalt mixtures and improves their engineering properties, except for the toughness index. Androjić and Dimter [23] replaced some of the aggregates and fillers in the asphalt mix with crushed glass and found that increasing the percentage of glass reduced the density, stability, and void content of the mix. Jin et al [24] used cathode-ray tube glass powders to modify asphalt, and the results revealed that cathoderay tube (CRT) glass powders may be recycled in asphalt binders as an environmentally beneficial recycling technology, with a CRT glass powder addition percentage of up to 10%.…”

Non-metallic fractions (NMFs) from waste printed circuit boards (PCBs) are mostly composed of cured resin and fiber. In this study, NMF material from a PCB was ground into powder and added into matrix asphalt to produce PCB-NMF-modified asphalt. To improve the compatibility of PCB-NMF and asphalt, a compatibilizer consisting of tung oil and glycerol was also developed. The optimum compatibilizer content was determined to be 8% by weight of the PCB-NMF through a series of laboratory tests, including the softening point, penetration, ductility, and softening point difference (SPD). The micro-mechanism of NMF powder-modified asphalt was analyzed through Fourier transform infrared spectroscopy (FTIR) and a scanning electron microscope test (SEM). The performances of PCB-NMF-modified asphalt were evaluated by the dynamic shear rheology (DSR) test and the low-temperature bending beam rheometer (BBR) test. The optimum compatibilizer content was 8% by weight of the NMF powder and the optimum content of NMF powder was determined to be 30% by weight of the asphalt based on a comprehensive evaluation. The results show that PCB-NMF can significantly improve stiffness, rutting resistance, high-temperature stability, and temperature sensitivity of asphalt material at an appropriate content. The BBR tests revealed that PCB-NMF slightly weakened the cracking resistance of asphalt at low temperatures. The SEM test showed that the addition of a compatibilizer can increase the compatibility by making the NMF powder evenly dispersed. The FTIR test results implied that a chemical reaction may not have happened between PCB-NMF, compatibilizer, and the matrix asphalt. Overall, it is a promising and sustainable way to utilize PCB-NMF as a modifier for asphalt material and reduce electronic waste treatment at a low cost.

“…Moreover, glass waste was one of the materials that was widely used as an alternative for both cement and aggregate in concrete [30][31][32][33][34]. In addition, glass waste was implemented as an eco-alternative to aggregates in asphalt mixtures in most of the flexible pavement layers, especially in the lower, coarser layers [35][36][37]. In addition, some research focused on the replacement of bitumen with glass powder in small ratios up to 10% [38,39].…”

Sustainable Valorisation of Silane-Treated Waste Glass Powder in Concrete Pavement

This research presents new insights into the utilisation of waste glass powder in concrete pavements. Two different types of glass powder were used as a partial replacement for sand: 10% neat glass powder (untreated) and 10% silane-treated glass powder. The interfacial bonding properties, physical properties, and mechanical properties of concrete pavement were assessed at 7 and 28 days. Results exposed a reduction of 5% and 2% in the compressive and flexural strengths, respectively, and an increase of 15% in water absorption after the addition of neat glass powder to concrete after 7 days of curing. This is due to weak interfacial bonding between the glass powder and cementitious matrix. However, the incorporation of silane-coated glass powder led to an increase in the compressive and flexural strengths by more than 22% and 28%, respectively, and reduced the water absorption of concrete by 8%, due to the coupling functionality of silane. After 28 days of curing, the compressive strength of concrete increased by 15% and 22% after the addition of neat glass powder and silane-treated glass powder, respectively. In addition, water absorption dropped by 5% and 7% after the incorporation of neat glass powder and silane-treated glass powder.
