Crumb rubberized asphalt binder achieves value-added recycling of waste scrap tires, as well enhancement mechanical properties and aging resistance pavements. This paper provides a systematic literature review the evolution sustainability implications crumb based on peer reviewed publications during 1993–2022. The analysis shows that methods, chemical-microstructural characterization, rheological-mechanical properties, environmental benefits are main research directions in studying binder....
Abstract Advancing sustainable materials requires addressing their environmental impacts, particularly emissions. This study contributes to the development of sustainable, non‐emitting asphalt by providing a detailed understanding diffusion and adsorption behaviors hazardous organic compounds (HOCs) emitted from asphalt. Using molecular simulations quantum analysis, it is investigated how characteristics sulfur‐ oxygen‐containing HOCs change as aging progresses in The results show that...
Asphaltene isomers proposed using Clar sextet theory. the new arrangement of aromatic rings optimizes location pi-sextets.
Bio-oil from biomass pyrolysis is a promising alternative and clean source of biofuels, chemicals, materials. Its chemical composition, physical properties, multiphase behavior change over time, because aging, which significantly affects its storage, handling, transportation, upgrading, application. This Review focuses on studying bio-oil outlook, primarily covering the following four components: (1) bio-oil; (2) indicators for measuring degree aging characteristics, including properties...
This study introduces iron-rich biochar to selectively adsorb some volatile organic compounds (VOCs) emitted from asphalt-surfaced areas. Adsorption and retention of VOCs can improve the air quality while reducing asphalt's mass loss which compromises durability. The was made a hybrid feedstock Cyanidioschyzon merolae (CM) algae swine manure (SM) with blend 20:80 CM/SM, showing highest yield 27 wt % metal content Fe (21.8 g kg–1). Comparison VOC adsorption low-iron shows significant role in...
Asphalt-paved surfaces have been reported as an important and long-lasting potential source of emissions a complex mixture volatile organic compounds into the atmosphere. Accelerated aging asphalt under high temperatures sunlight exposure is closely related to mass loss due asphalt-related emissions. This paper studies capability biomodifiers retain oxygenated in bitumen thereby extend bitumen's durability. It hypothesized that phenolic enhance intermolecular interactions with would...
The surface functionalization of silica nanoparticles (SiNPs) to enhance their compatibility and miscibility in the organic medium bitumen has been performed using various coupling agents. 3-Aminopropyl triethoxysilane (APTES) 3-glycidyloxypropyl trimethoxysilane (GPTMS) are among effective silanization agents; successful performance is attributed unique properties imparted by bifunctional characteristics. Here we study interaction mechanisms controlling process that lead distinct...
This paper examines the merits of using a hybrid bio-oil derived from algae and swine manure to rejuvenate aged bitumen by restoring properties which are degraded during oxidative aging. Nitrogen-containing compounds have been found be effective for decreasing size molecular agglomerates intensified aging provided they adequately penetrate into oxidized asphaltene agglomerations. The enhancement effect is mainly attributed their electronic structures, including polar head hydrocarbon tail...
This study decouples effects of ultraviolet (UV) exposure on the surface and bulk properties bituminous composites. UV accelerates oxidative aging bitumen, but its are concentrated mostly at bitumen. Here, we examine morphology chemical composition surfaces non-aged thin films bitumen UV-aged using combined atomic force microscopy (AFM) photothermal infrared (AFM–IR) spectroscopy; further compare findings with those measured by Fourier transform spectroscopy. The results showed that 20 h...
Moisture damage is one of the most intractable and costly pavement problems. Acid compounds in bitumen are implicated increased risk moisture at bitumen–aggregate interface, especially cases where siliceous aggregates used structure. This paper examines efficacy using active mineral powders as dopants to control migration alkane acids interface stone aggregates. Results from combined atomic force microscopy infrared spectroscopy (AFM-IR) confirm that accumulate bitumen–silica which turn...
