Abstract

Tire-pavement noise is a major contributor to traffic noise pollution, impacting human health and well-being. The advent of 3D printing and prefabrication technologies makes it feasible to economically produce delicate concrete pavement textures for noise mitigation. However, relationships between the noise and texture characteristics (e.g., cavity shape, width, depth, and spacing) remain unknown. This study developed an analytical model for tire-pavement noise and calibrated/validated the model using On-board Sound Intensity tests on a purposely constructed road section with manufactured texture configurations. These textures were found to be capable of reducing the noise level by 8–15 dB(A) over conventional concrete textures, and the model prediction closely matched experimental data. Subsequently, the model was used to investigate the texture-noise relationships and identify those major influencing factors. This study contributes to tire-pavement noise modeling and offers insights for building quieter concrete pavements and enhancing the urban living environment.

通过纹理诱导静音路面缓解交通噪音：分析模型和实地测试

轮胎路面噪声是交通噪声污染的主要因素，影响着人类的健康和福祉。三维打印和预制技术的出现，使得以经济的方式生产精致的混凝土路面纹理来缓解噪声成为可能。然而，噪声与纹理特征（如空腔形状、宽度、深度和间距）之间的关系仍然未知。本研究建立了一个轮胎路面噪声分析模型，并使用车载声强测试对模型进行了校准/验证。结果发现，与传统的混凝土纹理相比，这些纹理能够将噪声水平降低 8-15 dB(A)，而且模型预测结果与实验数据非常吻合。随后，该模型被用于研究纹理与噪声之间的关系，并确定主要影响因素。这项研究为轮胎路面噪声建模做出了贡献，并为建设更安静的混凝土路面和改善城市生活环境提供了启示。

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.
