Bitumen is a commonly used material for road construction. According to environmental regulations, vegetable-based materials are applied for binder modification. Fluxed road bitumen containing a bio-flux oxidation product increases the consistency over time. The efficiency of crosslinking depends on the number of double bonds and their position in the aliphatic chain of fatty acid. The main goa...

As the electrochemical method, the Fast Fourier Transform (FFT) Stripping Cyclic Voltammetry detection method was designed for measurement and monitoring of adsorbed mercury ions by new modified adsorbent based on mesoporous silica as a new adsorbent. In this respect, SBA-15 as mesoporous silica and 1, 3, 5 Trithiane as effective modifier ligand were chosen, and the modification process was car...

Transportation infrastructure relies heavily on asphalt pavement, but conventional bitumen-based mixtures present several drawbacks. This study assesses the potential of poly(methyl methacrylate) resins and thixotropic fillers as substitutes for bitumen to improve pavement performance. The research concentrates enhancing current formulations that incorporate a thermosetting polymer mineral (sti...

In this study, the recycled PET is used in bitumen modification by applying a different process order to eliminate phase separation problem. For purpose, modified bitumens are obtained adding triethanolamine (TEOA) chemical (wt. 2.5 %) and 2, 4, 6, 8, 10 pure bitumen. The properties of determined chemical, physical, rheological tests. According test results, reacts with PET, 6 % ratio critical ...

Compared with pure silica-based or organic-polymer monoliths, hybrid organic-silica monoliths offer the combined advantages of mechanically strong stationary phases, simpler preparation protocols, resistance to swelling and shrinking in many solvents and better pH stability. Comprehensive data on the systematic characterization of the pore space morphology of hybrid organic-silica monoliths and...

Stone mastic asphalt (SMA) has become widely used in the field of pavement engineering. Using specific additives SMA is necessary due to climate change and load condition variations. Thus, it essential utilise a modern mixture with high capacity survive traffic loads. The current study aims use combination waste polyethene terephthalate (PET) Nano-silica (NS) as newly developed hybrid additive ...

Flexible pavements are mostly affected by meteorological factors in addition to traffic loads, which results premature pavement failures like rutting and moisture-induced damage. This study focuses on the impacts of adding various contents nano-silica (NS), i.e., 2%, 4%, 6%, 8% (percentage weight asphalt), along with a constant value 4.5% styrene-butadiene-styrene (SBS). To assess effectiveness...

As an environmentally friendly alternative for the production of high-performance modified asphalt by chemical reactions, a liquid-state polyurethane-precursor-based reactive modifier (PRM) was developed and employed in modification. In contrast to traditional solid bitumen modifier, example, rubber thermoplastic elastomers, PRM as liquid has more significant advantages reducing energy consumpt...

Waste polymers are widely used in asphalt modification, especially, order to reduce their detrimental effect on the environment. This study discusses usability of waste expanded polystyrene (EPS) foam modification. In this respect, EPS foam, which produces both production and use stages, was mixed with bitumen by weight at ratios 2%, 4%, 6%, 8%, dry modification method employed. The penetration...

The effectiveness of weight ratio mineral filler to effective bitumen in the fatigue performance asphalt mixture with integral granules was investigated based on experiments mastic (mixture and passed through sieve grade 200). included a dynamic shear rheometer, elastic recovery, linear amplitude sweep tests other mixture, such as indirect tensile resilient modulus test for assessing medium tem...
