Abstract

Heavy traffic and climatic loads can accelerate road deterioration and the subsequent material consumption and waste generation from road maintenance. In Bangkok, Thailand, the lack of statistical records on this pressure necessitates the modeling and mapping of material movement. Therefore, this study combines Highway Development and Management System-4 and bottom–up approaches to conduct a spatiotemporal material flow analysis of Bangkok's roadway rehabilitation from 2004 to 2022. The findings reported an over threefold increase in material flow for pavement repair and revealed a spatial connection among this growth, the escalation of traffic and climate pressures, and the expansion of aging and less durable paved roads. In addition to having the strongest effect on traffic volume, the annual flood cycle was a crucial driver of substantial material use and waste. This is the first study to reveal the socioeconomic and environmental impacts of road repairs on material flows.

交通和气候状况如何加剧曼谷道路基础设施的材料消耗和浪费？

繁忙的交通和气候负荷会加速道路的恶化，以及随后在道路养护过程中产生的材料消耗和废物。在泰国曼谷，由于缺乏关于这种压力的统计记录，因此必须对物质运动进行建模和绘图。因此，本研究结合公路发展与管理系统-4和自下而上的方法，对2004 - 2022年曼谷道路修复进行了时空物质流分析。研究结果表明，用于路面维修的物料流量增加了三倍以上，并揭示了这种增长与交通和气候压力的升级以及老化和不耐用的铺装道路的扩张之间的空间联系。除了对交通量产生最强烈的影响外，每年的洪水周期也是大量材料使用和浪费的关键驱动因素。这是第一个揭示道路维修对物质流动的社会经济和环境影响的研究。

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.
