Abstract

Aiming to address the lack of available and accurate runoff coefficients of various roads in urban flooding simulations and effectiveness assessments of permeable pavement on runoff reduction, the rainfall-runoff response characteristics of typical urban road pavements were investigated by laboratory-scaled tests. The results showed that average runoff coefficients and initial runoff times of pervious road pavements were almost 0.1 ∼ 0.2 and 7 ∼ 20 times those of impervious pavements, respectively. Moreover, permeable brick (PB) pavement presented better capacity for runoff mitigation than permeable asphalt concrete (PAC) pavement when the average rainfall intensity was 1.11 or 1.80 mm/min. The average runoff coefficient of cement concrete (CC) pavement ranged from 0.939 to 0.985 under all rainfall intensity and longitudinal slope combinations, while that of asphalt concrete (AC) was between 0.907 and 0.961. These results may be beneficial to improving the precision of runoff computation generated from roads or other site areas in urban flooding simulations.

基于实验室测试的典型城市道路降雨径流响应特性

为了解决在城市洪水模拟和透水路面减少径流效果评估中缺乏各种道路的可用和准确径流系数的问题，通过实验室规模试验研究了典型城市道路路面的降雨-径流响应特性。结果表明，透水路面的平均径流系数和初始径流时间几乎分别是不透水路面的 0.1 ∼ 0.2 倍和 7 ∼ 20 倍。此外，当平均降雨强度为 1.11 或 1.80 毫米/分钟时，透水砖（PB）路面比透水沥青混凝土（PAC）路面具有更好的径流减缓能力。在所有降雨强度和纵坡组合下，水泥混凝土（CC）路面的平均径流系数在 0.939 至 0.985 之间，而沥青混凝土（AC）路面的平均径流系数在 0.907 至 0.961 之间。这些结果可能有助于提高城市洪水模拟中道路或其他场地产生的径流计算精度。

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.
