This review critically evaluates the role of Life Cycle Assessment (LCA) and Environmental Product Declarations (EPDs) in quantifying and mitigating these impacts, with attention to how system boundaries, Product Category Rules (PCRs), and background datasets influence reported outcomes. Drawing on over 500 peer-reviewed studies, the manuscript synthesizes evidence on material and process-level strategies, such as warm-mix asphalt (WMA), high-reclaimed asphalt pavement (RAP) content, cold in-place recycling, bio-based binders, and waste derived additives, that demonstrate measurable reductions in life cycle indicators across different scope boundaries.</div><div>This study highlights the emerging potential of digital technologies.

Together, these tools support the development of dynamic, high-resolution environmental profiles that improve transparency and comparability. Policy developments across the United States, European Union, and other regions illustrate how EPDs are becoming embedded in public procurement practices, with growing alignment around EN and ISO standards enhancing consistency and cross-border comparability. Despite recent advancements, several key challenges still remain unresolved, including fragmented PCR frameworks, limited high quality datasets for emerging materials, and uncertainty in modeling long-term pavement performance. To address these, this review proposes a roadmap focused on standardized impact reporting, direct measurement of material and energy flows, and verifiable digital workflows. Overall, the findings support a shift from static environmental documentation to actionable, performance-based tools that promote cleaner asphalt materials and sustainable infrastructure development.</div></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"18 ","pages":"Article 100346"},"PeriodicalIF":9.0,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145269898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reliable point-contact diffusion models were established and validated by density and glass transition temperature calculations, confirming the accuracy of our molecular representations. Differences in solubility parameters between systems were quantitatively analyzed to assess compatibility. Temperature-dependent molecular mobility was characterized through mean square displacement and diffusion coefficient calculations across virgin, aged, and rejuvenated asphalt systems. The layered-contact diffusion models were developed to calculate fusion coefficients, providing quantitative metrics for evaluating TWCO’s effectiveness in restoring the diffusion and fusion capabilities of aged asphalt. Furthermore, interfacial binding energies between heterogeneous material systems were computed to investigate interface stability. Experimental validation was conducted using Fourier-transform infrared spectroscopy to track functional group evolution and atomic force microscopy to assess microstructural recovery. Key findings demonstrated that the solubility parameter differences between TWCO and aged asphalt, as well as between rejuvenated and virgin asphalt, were consistently below 2.1 (J·cm⁻³)^1/2, indicating excellent compatibility. Across all simulated temperatures, the diffusion coefficients of rejuvenated asphalt exceeded those of aged asphalt, confirming partial restoration of molecular diffusion capacity and microscopic mobility in the aged system. Moreover, compared to the virgin-aged asphalt interface model, the TWCO-rejuvenated system exhibited significantly enhanced fusion coefficients, interfacial energy, and work of adhesion. After TWCO incorporation, the peak intensities of polar functional groups in aged asphalt progressively diminished, while surface homogeneity improved—evidenced by increased quantity yet reduced size of “bee-like structures” and lower roughness parameters.

This study proposes a novel ternary cementitious system composed of SS, fly ash (FA), and cement, utilizing TS and TM generated from the shield tunneling construction on the Tianxiang Avenue section of Nanchang as fine aggregates for the preparation of synchronous grouting materials. The mechanical, rheological, hydration characteristics, and hardening mechanisms of the developed grouting materials were systematically evaluated. The results show that when the SS content is 20 %–30 % and the TS:TM ratio is 7:3, the 28-day unconfined compressive strength (UCS) reaches 5.85 MPa, which is 24.5 % higher than that of the traditional cement-FA system. Additionally, the flow diameter of the slurry increases to 280 mm, and the bleeding rate is reduced to less than 1 %. At 20 % SS content, the slurry’s yield stress and viscosity significantly increase, enhancing structural stability. However, excessive SS content weakens the network integrity. As the TS:TM ratio increases, the yield stress and thixotropy of the slurry also increase. Mechanistic analysis indicates that the highly alkaline microenvironment generated by the early hydration of cement clinker promotes the depolymerization of the amorphous phase in SS and the aluminosilicate glass phase in FA. The hydroxyl ions released by the hydration of SS further accelerate the dissolution and reaction of the active components in FA, significantly promoting the formation of C-S-H gel and densifying the skeleton structure. The Ca²⁺ provided by the FA participate in the formation of C-S-H, resulting in a pronounced synergistic effect. This study elucidates the synergistic activation mechanism of shield muck and SS and their coupled impact on the macro- and micro-performance of the grouting material. It provides a theoretical basis and engineering strategy for the high-value utilization of shield muck in backfill grouting, which aligns with the principles of cleaner production and sustainable material engineering by turning waste into valuable resources, reducing carbon footprint, and minimizing environmental impact.</div></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"18 ","pages":"Article 100341"},"PeriodicalIF":9.0,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145099343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
