摘要

本研究通过在石油沥青中加入稻草和轮胎等废弃材料，解决了沥青路面施工对气候变化的影响。我们扩大了生命周期评估（LCA）的范围，以量化道路建设各个阶段的碳排放，包括能源消耗和高温释放。我们比较了废弃物副产品燃烧与利用这些废弃物资源生产改性沥青对环境造成的负担。通过中国的实际重建案例，研究发现总排放量的 70% 以上来自材料生产和混合。避免高温焚烧原材料所减少的碳排放量与生产改性沥青所减少的碳排放量几乎相等。研究结果表明，在道路工程中使用废弃材料不仅能促进基础设施的可持续发展，还能帮助减少污染和碳排放，符合更广泛的环境保护目标。

Waste-modified asphalt for climate change mitigation: Carbon and pollution reduction

This study addresses climate change impacts from asphalt pavement construction by incorporating waste materials like rice straw and tires into petroleum asphalt. The life cycle assessment (LCA) boundary is expanded to quantify carbon emissions at various stages of road construction, including energy consumption and high-temperature releases. We compare the environmental burden of waste by-product combustion with that of producing modified asphalt using these waste resources. Through real reconstruction cases in China, the study reveals that over 70% of total emissions stem from material production and mixing. Carbon emissions reduced by avoiding high-temperature burning of raw materials are nearly equal to those of modified asphalt production. The findings suggest that incorporating waste materials in road engineering not only promotes sustainable infrastructure but also aids in pollution and carbon reduction, aligning with broader environmental conservation goals.

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
