Abstract

The adoption of Electric Vehicles (EVs), driven by policies like the Zero Emission Vehicle (ZEV) mandate, is rapidly transforming transportation infrastructure. In 2021, over 1.25-million light-duty EVs were registered in the United States, signaling a shift that extends to heavy vehicle categories. This study evaluates the implications of this transition on road networks, focusing on the increased gross weight of EVs compared to traditional Internal Combustion Engine (ICE) vehicles and its impact on flexible pavement structures. The study investigates the deterioration patterns and potential damage to road infrastructures resulting from integrating EVs into the traffic mix, utilizing both the AASHTO 1993 and Mechanistic-Empirical (ME) pavement evaluation methodologies. The analyses reveal a significant acceleration in road degradation, necessitating urgent consideration of EV-induced stresses by transportation authorities. Recommendations for future research and practical strategies for mitigating these impacts are provided to guide policymakers and engineers in adapting to this evolving vehicular landscape.

评估电动汽车负载对柔性路面可能造成的损坏

在零排放汽车 (ZEV) 规定等政策的推动下，电动汽车 (EV) 的采用正在迅速改变交通基础设施。2021 年，在美国注册的轻型电动汽车超过 125 万辆，这标志着向重型汽车类别的转变。本研究评估了这一转变对道路网络的影响，重点关注与传统内燃机（ICE）汽车相比，电动汽车总重量的增加及其对柔性路面结构的影响。研究采用 AASHTO 1993 和力学-经验（ME）路面评估方法，调查了电动汽车融入交通组合后对道路基础设施造成的损坏模式和潜在损害。分析结果表明，道路退化速度明显加快，因此交通管理部门有必要紧急考虑电动汽车引起的压力。本文还提出了未来研究建议和减轻这些影响的实用策略，以指导政策制定者和工程师适应不断变化的车辆环境。

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.
