“…The rapidly growing pavement industry in the last few decades and, consequently, increased vehicular traffic load, forced the attempts of quality improvement of the most sensitive component of asphalt concrete [ 7 , 10 ]. Therefore, various polymers have been utilized over the years as bitumen binder modifiers with an example of thermoplastic polymers (polyethylene [ 11 ], polypropylene [ 12 ], ethylene vinyl acetate or ethylene butyl acrylate [ 13 ]), thermoplastic elastomers (styrene-butadiene-styrene triblock copolymers (SBS) [ 13 , 14 ]), polycondensation resins (phenol-cresol-formaldehyde resins and phenol-formaldehyde resins with labile peroxy bonds or methacrylic components [ 10 , 15 ]), petroleum resins with epoxy, hydroxy or carboxy groups [ 16 ], low-molecular organic compounds (formaldehyde and maleic anhydride) [ 17 , 18 ], or recycled elastomers in the form of ground tire rubber [ 19 ].…”

With the continuing growth of waste sulfur production from the petroleum industry processes, its utilization for the production of useful, low-cost, and environmentally beneficial materials is of primary interest. Elemental sulfur has a significant and established history in the modification of bitumen binders, while the sulfur-containing high-molecular compounds are limited in this field. Herein, we report a novel possibility to utilize the sulfur/organic copolymers obtained via the inverse vulcanization process as modifiers for bitumen binders. Synthesis and thermal characterization (TGA-DSC) of polysulfides derived from elemental sulfur (S8) and unsaturated organic species (dicyclopentadiene, styrene, and limonene) have been carried out. The performance of modified bitumen binders has been studied by several mechanical measurements (softening point, ductility, penetration at 25 °C, frass breaking point, adhesion to glass and gravel) and compared to the unmodified bitumen from the perspective of normalized requirements concerning polymer-modified bitumen. The interaction of bitumen binder with sulfur/organic modifier has been studied by means of FTIR spectroscopy and DSC measurements. The impact of the modification on the performance properties of bitumen has been demonstrated. The bitumen binders modified with sulfur/organic copolymers are in general less sensitive to higher temperatures (higher softening point up to 7 °C), more resistant to permanent deformations (lower penetration depth), and more resistant to aging processes without intrusive deterioration of parameters at lower temperatures. What is more, the modification resulted in significantly higher adhesion of bitumen binders to both glass (from 25% up to 87%) and gravel surfaces in combination with a lower tendency to form permanent deformations (more elastic behavior of the modified materials).

The characteristics of initial crudes of Yablunivske field (Poltava, Ukraine) and the properties of blended crudes have been examined to select the ways of their further processing. The crude oils were found to be heavy high-sulfuric oils without light distillates. The possibility of obtaining paving bitumen from blended crudes under study has been considered. Distilled bitumen obtained through distillation of this blend was found to meet the requirements for commercial paving bitumen 100/150. To improve the durability and resistance to aging of resulting bitumen, a polymeric modifier was added. The modifier amount of 3 wt.% was found to be appropriate to improve the operational characteristics of obtained bitumen to those of BMW 60/90 grade.

“…The interesting approach is bitumen production due to tar chemical modification with low-molecular compounds, with formaldehyde 16,17 or maleic anhydride, 18 in particular. According to this approach, it is unnecessary to modify the obtained bitumen with polymers or resins because its modification occurs due to the chemical modification of tar.…”

“…The formed areneformaldehyde resins are modifiers of bitumen properties on the one hand, and on the other hand, the transition of oils into resins takes place, 19 which also improves the bitumen properties. When petroleum residue is modified with maleic anhydride, 18 the molecules of anhydride react with bitumen components. This also allows to improve the bitumen properties due to the additional introduction of compounds with hydroxy groups.…”

Hydroxyapatite nanoparticles were isolated from a biowaste, buffalo bone, via the thermal decomposition method. The resulting white powdered material was characterized by Fourier Transformed Infrared (FTIR) spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray (EDX) analysis. The FTIR spectra confirmed that a heat treatment of the bone powder at the temperature at or above 1223 K removed the organic moieties leading to the formation of a pure inorganic biomineral. The XRD analyses showed that the obtained material was nanocrystalline HAp (nano-HAp) with an average grain diameter of 25 nm, while their rod-shaped particles with their tightly agglomerated morphology were confirmed by the SEM analysis. Besides Calcium (Ca), Phosphorous (P), and Oxygen (O), trace amounts of Aluminum (Al), Magnesium (Mg), Copper (Cu), Zirconium (Zr) and Carbon (C) were also found by EDX analysis. Antibacterial activity of nano-HAp against six standard isolates was investigated by the agar well diffusion method and found to be more susceptible to Acinetobacter baumannii while other standard strains such as Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus showed lesser susceptibility and no antibacterial activity was noticed against Salmonella typhi and Methicillin resistant Staphylococcus aureus (MRSA) with the analysed concentration of nano-HAp suggesting its potential application in biomedical fields.
