However, current indicators for evaluating asphalt foaming performance are largely singular and fixed, failing to reflect the variable temperature, water content, and equipment conditions in actual asphalt plants. Similarly, existing methods for determining optimal foaming conditions rely on laboratory-fixed settings or single metrics, limiting their applicability and reliability for practical field production. In this study, the asphalt foam collapse test (AFCT) was conducted on 70# asphalt, 90# asphalt, and SBS-modified asphalt using a laser sensor system. Based on the four evaluation indicators—expansion ratio (ER), half-life (HL), foam index (FI), and surface area index (SAI)—the foaming performance of three types of asphalt was comprehensively analyzed. Subsequently, the effects of varying water content and foaming temperature on these two indicators were investigated. Unlike the monotonic trends observed in expansion ratio and half-life, both FI and SAI exhibited peak values under specific conditions. Building upon this analysis, interpolation and simulation methods using MATLAB were employed to develop an optimization approach for determining the optimal foaming conditions. Furthermore, the rationality of the proposed optimization method was verified through workability and coating tests of foamed asphalt mixtures. The results demonstrate that the proposed method yields a range of optimal foaming temperatures and water contents rather than a single fixed value, making it more consistent with practical engineering applications.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"519 ","pages":"Article 145895"},"PeriodicalIF":8.0,"publicationDate":"2026-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147388212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study systematically investigates the shear performance and failure mechanisms of SCBSB-reinforced concrete beams using four-point bending tests. The key parameters examined are the shear span ratio, the stirrup ratio and the reinforcement type (clad stainless steel, solid stainless steel, conventional steel). The influence of these parameters on the failure mode, stiffness development, crack propagation, ultimate load capacity and deformation capacity is examined. The relative importance of these factors is quantified using the SHapley Additive exPlanations (SHAP) method. The results indicate that for shear span ratios between 1 and 3, the SCBSB beams exhibit a typical shear-compression failure mode. The shear capacity increases significantly with a higher stirrup ratio and a lower shear-span ratio, outperforming conventional reinforced concrete beams under equivalent conditions. Furthermore, the width of the critical diagonal crack increases with the shear-span ratio. SHAP analysis reveals that stirrup spacing is the most critical factor influencing the load-carrying capacity, followed by the stirrup ratio and the fracture elongation of the steel reinforcement. This highlights the dominant influence of structural detailing and material ductility on shear performance. Based on the experimental data and mechanistic analysis, a calculation formula for the shear capacity of SCBSB beams is proposed. The calculated values show strong agreement with the experimental results, providing a theoretical basis for the engineering design and optimization of such components. This study clarifies the shear failure mechanisms and key influencing factors for SCBSB beams, thereby providing an important reference for promoting the application of these highly ductile and durable stainless steel-clad rebars in concrete structures.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"519 ","pages":"Article 145882"},"PeriodicalIF":8.0,"publicationDate":"2026-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147388220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, their simultaneous achievement presents a fundamental challenge. This inherent trade-off originates from the low solubility of highly crosslinked polymers, which impedes penetration and compromises consolidation efficacy. In this study, an efficient in situ crosslinking strategy is proposed to break this trade-off by employing a thiol-functionalized polyorganosiloxane precursor adhesive. This precursor achieves deep infiltration, followed by crosslinking via synergistic solvent-induced self-assembly and Fe³ ⁺ catalysis. Theoretical calculations corroborate that this synergy reduces the energy barrier for disulfide bond formation by 35.4%, enabling controlled in situ crosslinking without damaging painted architectural relics. Moreover, the adhesive demonstrates robust cohesive strength, enabling consolidated samples to maintain stability at 85% RH. These capabilities enable the adhesive to achieve not only stable consolidation but also effective restoration for fragile painted architecture. By modulating the crosslinking density within the flaking pigment layers, the adhesive reduces their elastic modulus by 99.8%, thereby plasticizing the brittle paint and facilitating successful reattachment. The restored regions retain structural integrity even after 1500 h of dry-wet cycling, demonstrating long-term durability. This in situ crosslinking strategy provides an avenue for integrated conservation of cultural heritage.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"519 ","pages":"Article 145788"},"PeriodicalIF":8.0,"publicationDate":"2026-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147388222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, distribution, diffusion, and interaction pathways of the two types of rejuvenators within aged SMB may interfere with each other, which could compromise rejuvenation effectiveness and have not been thoroughly investigated to date. In order to investigate the synergistic mechanism between reactive and conventional rejuvenators, a composite reactive rejuvenator consisting of bio-oil and the epoxy compound was developed, and five rejuvenation strategies were proposed. The effectiveness of each strategy was evaluated through the physical property test, toughness test, and rheological test. Moreover, the rejuvenation mechanism and synergistic interaction pathways were explored using Fourier transform infrared spectroscopy and fluorescence microscopy tests. Results show that bio-oil helps restore the component balance of aged SMB but cannot repair broken SBS, whereas 1,6-hexanediol diglycidyl ether (HDE) is capable of chemically reconstructing the SBS network structure. As for the composite rejuvenation strategy involving HDE and bio-oil, bio-oil interferes with HDE effectiveness on degraded SBS. On one hand, bio-oil contains active compounds that engage in reactions with degraded SBS, on the other hand, they compete with degraded SBS to react with the epoxy compound. This interference significantly diminishes the effect of HDE on broken SBS and the crosslinking density of reconstructed SBS network structure, which results in decreased ductility, toughness, and high-temperature rutting resistance of rejuvenated SMB. It is imperative that the epoxy compound undergo complete reaction with degraded SBS beforehand to prevent interference caused by bio-oil, which eliminates potential active sites susceptible to reaction with bio-oil. These findings support a well-founded theoretical perspective and provide essential practical insights for the design of reactive rejuvenation strategies and the enhancement of effectiveness.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"519 ","pages":"Article 145900"},"PeriodicalIF":8.0,"publicationDate":"2026-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147388245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
