Abstract

Solid waste recycling is an essential approach for the sustainable transition of transportation infrastructure development. In this study, a holistic model for recycled waste pavement was developed, achieving a breakthrough in eco-efficiency-based pavement material design. Using this model, we can not only individually assess the technical feasibility of the pavement material and its carbon emissions, but also realize the unified dimensional quantification of multidimensional parameters based on decision-making expectations using a metrics fusion system, thus achieving high-level sustainability decisions for pavement schemes. The proposed model was validated by evaluating the comprehensive properties of steel slag pavements to determine a suitable and durable pavement solution. This study provides a decarbonization strategy for the transportation sector considering waste-recycled pavement design, which may promote the development of more resilient transportation infrastructure and significantly contribute to achieving carbon neutrality and mitigating climate change.

•
A model for solid waste pavement was established based on synthesized assessing feasibility and carbon emissions.
•
The field performance and climate system impacts of pavements with solid waste materials were assessed.
•
It was demonstrated that recycling steel slag for pavement construction can reduce carbon emissions by >50 %.
•
Our results contribute to achieving sustainable transportation infrastructure systems to mitigate climate issues.
•
Our methodology can be used not only for road construction but also in the civil engineering field.

评估再生废料路面性能和碳排放的双驱动融合模型

固体废弃物回收利用是交通基础设施可持续转型发展的重要途径。本研究建立了废弃物再生路面整体模型，在基于生态效益的路面材料设计方面取得了突破性进展。利用该模型，我们不仅可以单独评估路面材料的技术可行性及其碳排放量，还可以利用度量融合系统实现基于决策期望的多维参数的统一维度量化，从而实现路面方案的高层次可持续性决策。通过评估钢渣路面的综合特性，对所提出的模型进行了验证，从而确定了合适、耐用的路面方案。本研究提供了一种考虑废物回收路面设计的交通领域脱碳战略，可促进更具弹性的交通基础设施的发展，并为实现碳中和和减缓气候变化做出重要贡献。-我们的成果有助于实现可持续交通基础设施系统，以缓解气候问题。我们的方法不仅可用于道路建设，还可用于土木工程领域。

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
