Asphalt pavement, widely utilized in transportation infrastructure due to its favourable properties, faces significant degradation from chloride salt erosion coastal areas and winter deicing regions. In this study, two commonly used asphalt binders, 70# base SBS (Styrene–Butadiene–Styrene)-modified asphalt, were study the effect on pavement by immersing materials laboratory-prepared solutions. The conventional properties adhesion of assessed using penetration, softening point, ductility, pull-off tests, while Fourier transform infrared spectroscopy (FTIR) elucidated mechanism. Marshall stability test, freeze–thaw splitting Cantabro test applied effects exposure strength, water stability, structural integrity mixture. Finally, grey correlation analysis was employed assess impact performance binders mixtures. findings highlight that reduces penetration ductility both types raises weakens asphalt–aggregate adhesion, confirmed as a primarily physical FTIR analysis. mixtures showed decreased strength intensifying these impacts at higher concentrations longer duration. SBS-modified exhibited greater resistance erosion, particularly demonstrated pull-out tests. Grey relational revealed duration is most influential factor, with TSR point emerging responsive indicators chloride-induced changes. These offer critical insights for practice, providing evidence-based guidance designing constructing pavements environments high levels.

Deicing agents may compromise the performance of asphalt mixture. This article aims to study feasibility using styrene-butadiene-styrene (SBS)/crumb rubber (CR) modifier prepare a deicing mixture with satisfactory for ultra-thin wearing course. High/low-temperature performance, water stability and deicing-related performances were evaluated by conducting series laboratory tests from micro macro level considering different incorporation rates anti-freezing agent SBS/CR modifier. The results find that modification enhances high low-temperature properties binder, optimal ratios are 2% 16%, respectively. addition as filling material improves high-temperature mortar, but negatively affects performance. For mixtures, can enhance up 56%, only minor impact on anti-sliding properties. However, they harm stability. A recommended maximum replacement ratio 80% achieves in dynamic (11,053 times/mm), flexural strength (8.41 MPa), tensile strain (3011.08E−6), Marshall (9.61 residual (81.28%), free-thaw splitting (80.30%), meeting engineering standards. An Anti-freezing 20% 100% correlates linearly snow-melting rate 16.3%− 96.8% 9.4%− 57.0%. conductivity soaking solution has been identified valuable indicator predicting functionality. research provide insights into design facilitate practical implementation this innovative functional material.

Enhancing the performance and sustainability of asphalt materials is crucial for developing durable environmentally friendly infrastructure. This study explores impact bio-oils derived from biomass waste on water diffusion behavior biomodified bitumen, highlighting significance surface interactions in optimizing material properties. Through dewetting contact angle measurements differential Fourier transform infrared (FTIR) spectroscopy, we examine between bitumen. While improve bitumen adhesion, they also increase absorption, potentially weakening cohesion due to altered Salty showed distinct behavior, with FTIR analysis revealing changes composition salt complex formation bio-oil components. In presence a monovalent (NaCl), some binders performed significantly worse than others, variability salt-induced degradation among different formulations. Conversely, when exposed divalent solution (CaCl2), all blends exhibited great resistance dewetting. These findings emphasize role chemistry influencing under varied environmental conditions. Additionally, short-term thermal aging was shown diffusion, affecting both physical chemical properties Density functional theory (DFT) further elucidated how alters water–oil interactions, exacerbating diffusion. Our underscores need carefully refining formulations mitigate water-induced support sustainable, long-lasting solutions, especially environments prone exposure corrosive

The durability of asphalt pavement in coastal regions has been a widely discussed topic due to the coupling effect complex climate environment and seawater erosion. Aging-resistant materials (ARMs) significantly enhance resistance high-viscosity modified (HiMA), but their impact on asphalt–aggregate interface interaction erosion-induced failure remains unclear. In this study, molecular dynamics simulation was employed investigate molecular-atomic scale interactions at HiMA–aggregate evolution mechanism erosion with different ARMs. An analysis adhesion aging-resistant HiMAs conducted based polarity, component distribution, nanostructure evolution. ARMs were further investigated. research indicates that interact extensively components polymers, altering spatial arrangement characteristics HiMA aggregate interface. promote free volume diffusion ability molecules accelerate aggregation With addition ARMs, highly polar asphaltene resin intensify movement toward interface, exhibiting directional adsorption aggregates. Simultaneously, weakly polymer light detach from vacating active sites Consequently, Seawater induces water pathways leading intrusion ionic solutions into occupation sites, thereby diminishing direct between aggregate. reduces deterioration ion dissolution under erosion, thus improving Light shielding material exhibits most effective enhancement stability
