“…However, the scientific research has been focused also on different themes, for instance, the recycling of waste materials for the construction of road pavements, in order to save natural aggregates, which nowadays are less available [12][13][14][15][16][17][18][19][20][21][22]. Hence, the study of high performance hot mix asphalt, characterized by aggregate structures made with recycled materials, gives the possibility of meeting the demand of high mechanical resistance as well as that of sustainability of the road construction.…”

The paper introduces and analyses the results of an experimental trial on the fatigue resistance of recycled hot mix asphalt for road pavements. Based on the gyratory compaction and the indirect tensile strength test, the mix design procedure has optimized nine different mixes, considering both conventional limestone and Reclaimed Asphalt Pavement (RAP), the latter used at different quantities, up to 40% by weight of the aggregate. A standard bitumen and two polymer modified binders were used for the production of the mixes. The fatigue study was carried out with four-point bending tests, each one performed at 20°C and 10 Hz. The empirical stiffness reduction method, along with the energy ratio approach, based on the dissipated energy concept, was adopted to elaborate the experimental data. Unaged and aged specimens were checked, to analyse the ageing effects on the fatigue performance. In comparison with the control mixes, produced only with limestone, improved fatigue performance was noticed for the mixtures prepared with RAP, especially when made with polymer modified binders, under both aged and unaged conditions. Both the approaches adopted for the experimental data analysis have outlined the same ranking of the mixes.

Blast furnace slags (BFS) is a secondary byproduct of iron industry, which has a combination of acidic and basic oxides and show a complex, multiphase structure. If appropriately tailored, BFS could be an effective functional filler, improving the property profile of thermoplastics such as polypropylene (PP) and polystyrene (PS). As a raw material, the proposed filler may introduce both economic and ecological advantages, as it is considered an inexpensive secondary product rather than a natural resource. The current study aims at investigating the effect of incorporating BFS as a micro‐sized filler on the rheological, thermal, and mechanical behavior of PP and PS. BFS types in this study are air‐cooled, crystalline, and amorphous, grounded types. Both types are ground into 71, 40, and 20 μm batches and introduced in 10, 20, and 30 weight fractions via melt kneading. Mixtures are then formed into 4‐mm and 2‐mm thick plates via compression molding. Slight increase in rheological factors is observed with increasing filler loading. BFS hinders the crystallization of PP, resulting in slight increase of crystallization temperatures (Tc) and lowering of crystallization enthalpy (ΔHc). No significant effect of filler on transition temperatures (Tg) is reported. Mechanically, BFS increases the tensile modulus of PP, but decreases its strength. For PS formulations, a modest toughening effect is observed by slag filler. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43021.

Blast furnace slag (BFS) is a byproduct of the blast furnace in iron industry. Due to its composition and structure, BFS is suggested as a promising functional filler that can potentially improve the property profile of polypropylene. To overcome the lack of compatibility between BFS and polypropylene (PP), two coupling agents, vinylethoxysiloxane homopolymer silicon and methacryloxypropyltrimethoxysilane, are utilized for treating the BFS surface. The influence of each coupling agent on the BFS–PP compound properties is investigated in this work. It is observed that both coupling agents equally increase the complex shear viscosity and thermal conductivity of the modified BFS compounds by 10% and 12%, respectively, compared to their unmodified counterparts. The degree of crystallinity of the modified compounds also increased by more than 25%. While the tensile stiffness and yield strength levels are found to be comparable for all compounds, the strain at break of some modified BFS compounds is doubled. © 2018 Wiley Periodicals, Inc. J.
