“…On the other hand, the MW filler shows a water content value strictly comparable to limestone filler. Other studies have recorded water content values generally lower than 1.5% (e.g., 0.79% for hydraulic lime, 1.36% for hydrated lime, 0.21% for Portland cement and 0.04% for basaltic filler) [46].…”

“…Some studies assess that the bituminous mixture performaces are enhanced with R & B delta values between 12 and 16 • C [49]. However, the Ring and Ball delta, as set out in EN 13043 for traditional fillers, ranges between 8 and 16 • C. For example, researchers assessed a variation in R & B temperature equal to 6.8 • C for basaltic filler, 7.8 • C for Portland cement and 14 • C for hydrated lime [46,53]. The mud waste filler and the glass powder filler comply with these values.…”

“…MW and Gl fillers have similar RV values, in line with the lower limit of the EN 13043 standard. However, even if Ud has the highest RV value, previous studies and research have highlighted high values for fillers often used for the production of asphalt concretes (e.g., RV = 71% for hydrated lime, 51% for hydraulic lime or 45% for Portland cement) [46]. • Some relationships could exist between the Ring and Ball temperature and the percentage of Rigden Voids.…”

There has been a significant increase in the demand for using recycled materials in construction because of the lack and limitation of available natural resources. A number of industrial and domestic waste products are being used in the replacement of traditional materials for road construction, and many studies have been carried out in recent years on the use of different recycled materials in substitution of conventional fillers in Asphalt Concretes (AC). The aim of this laboratory research is to analyze the physical characteristics of three different recycled fillers and compare them with those of a traditional limestone filler. The alternative fillers presented in this paper are: a waste bleaching clay that comes from two consecutive stages in the industrial process for decolouring vegetable oils and producing biogas (Ud filler), a dried mud waste from a tungsten mine (MW filler) and a recycled glass powder (Gl filler). Results show significant differences between the fillers, and, in particular, Rigden Voids (RV) seem to have the largest potential influence on the rheology of ACs.

“…Based on the results obtained on bitumens, the aim of this study is to assess if the same approach can be reliably extended also to mastics in order to evaluate possible effects on thixotropy and self-healing capability due to the presence of filler. To this purpose, as suggested by Antunes et al [25], the influence of filler morphology in the filler-bitumen interaction was also considered by means of SEM imaging.…”

“…Fillers are used in GBR-B with the intent of increasing stiffness and strength and also filling the voids in the hot mixture [2]. The filler is not only natural aggregates such as calcite, but also lime, lignin, sulfur, or ultrathin cut fiber particles which could pass number 200 (0.075 mm) sieve [3].…”

Bituminous geomembranes, one type of geosynthetics, include a hot bituminous mixture with mineral filler and reinforcement. In this study, boron production waste clay (CW) was used as filler to produce a geosynthetic barrier with bentonite, waste tire, and bitumen. Bentonite and waste tires were used as auxiliary fillers and bitumen as the binder. CW/bitumen, CW/bentonite/bitumen, and CW/waste tire/bitumen mixtures were prepared by using a laboratory mixer at 100 ∘ C. Hot mixtures were extruded into strips by using a lab-scale corotating twin screw extruder (L/D: 40) followed by die casting (2 mm × 100 mm). Glass fleece or nonwoven polyester was used as reinforcement material and while die casting, both sides of the reinforcement materials were covered with bituminous mixture. Thickness, mass per unit area, tensile strength, elongation at yield, and hydraulic conductivity were used to characterize the geomembranes. Among all geomembranes, nonwoven polyester covered with 30% bitumen-70% boron waste clay mixture (PK-BTM30CW70) was found to be the most promising in terms of structure and mechanical behaviour. After that, consequences of its exposure to distilled water (DW), municipal solid waste landfill leachate (L-MSW), and hazardous waste landfill leachate (L-HW) were examined to use for an innovative impermeable liner on solid waste landfills.
