Abstract

Road infrastructure plays an important role in strengthening transportation and driving the economic advancement of countries. However, the increasing traffic volume has accelerated road deterioration, particularly at critical points like bridge-road junctions. Traditional repair methods involving demolition and reconstruction lead to extended closures and high costs. This study explores the polyurethane (PU) foam injection technique as an alternative solution, which can reduce both repair time and costs. The research evaluates the application of PU foam in various road projects across Thailand, highlighting its ability to repair pavement surfaces and structures, even in severely damaged areas. Despite its advantages, the use of PU foam faces challenges due to a lack of standardized quality control. This paper proposes a set of working guidelines for PU foam injection, aimed at key stakeholders such as the Department of Highways, the Department of Rural Roads, and the Department of Local Administration. The findings underline the importance of establishing standardized methods to ensure the long-term effectiveness of PU foam in road maintenance. Future research should focus on refining these guidelines for diverse road conditions to support the sustainable development of national transportation infrastructure.

用于道路养护的聚氨酯泡沫注射技术的性能

道路基础设施在加强交通和推动国家经济发展方面发挥着重要作用。然而，日益增长的交通量加速了道路的老化，尤其是在桥梁与道路交界处等关键位置。传统的维修方法包括拆除和重建，导致长时间的封闭和高昂的成本。本研究探讨了聚氨酯（PU）泡沫注射技术，将其作为一种可缩短维修时间并降低成本的替代解决方案。研究评估了聚氨酯泡沫在泰国各种道路项目中的应用，强调了其修复路面表面和结构的能力，即使是在受损严重的地区。尽管聚氨酯泡沫具有诸多优势，但由于缺乏标准化的质量控制，其使用仍面临挑战。本文针对公路部、农村道路部和地方行政部等主要利益相关方，提出了一套聚氨酯泡沫注入工作指南。研究结果强调了建立标准化方法的重要性，以确保聚氨酯泡沫在道路养护中的长期有效性。未来的研究应侧重于针对不同的道路条件完善这些准则，以支持国家交通基础设施的可持续发展。

期刊介绍： Transportation Geotechnics is a journal dedicated to publishing high-quality, theoretical, and applied papers that cover all facets of geotechnics for transportation infrastructure such as roads, highways, railways, underground railways, airfields, and waterways. The journal places a special emphasis on case studies that present original work relevant to the sustainable construction of transportation infrastructure. The scope of topics it addresses includes the geotechnical properties of geomaterials for sustainable and rational design and construction, the behavior of compacted and stabilized geomaterials, the use of geosynthetics and reinforcement in constructed layers and interlayers, ground improvement and slope stability for transportation infrastructures, compaction technology and management, maintenance technology, the impact of climate, embankments for highways and high-speed trains, transition zones, dredging, underwater geotechnics for infrastructure purposes, and the modeling of multi-layered structures and supporting ground under dynamic and repeated loads.
