由于各种原因造成的道路建设项目延误是建筑专业人员面临的一个主要问题。无法在既定预算内按时完成项目是世界范围内的一个长期问题。这项研究旨在确定地球仪上25个发展中国家公路建设项目延误的十大主要原因。这项研究包括两个步骤。首先，作者汇编了关于道路建设项目中最常见的延误的信息。其次，他们分析了这些项目中每种延误原因的强度。考虑到信息的性质，研究人员在方法上更加准确，使用了准元分析来处理数据。一半（50%）的国家有类似的延误原因，同样，50%的国家根据强度结果确定了道路建设项目延误的十大主要原因。本研究使用了强度的结果。根据认证结果，施工经理缺乏经验、规划/进度安排不当以及对道路建设项目沿线的人的土地的影响（为项目建设征用土地）比设计的频繁变更（被列为最常见的延误原因）影响更大。
Delays in road construction projects due to various reasons are a major problem facing construction professionals. The incapability of finishing projects punctually and within a given budget is a persistent issue worldwide. This study aims to determine the ten principal causes of delay in road construction projects in 25 developing countries across the globe. The study involves two steps. First, the authors compiled information regarding the most frequent delays in a road construction project. Second, they analyzed the intensity of each cause of delay in these projects. Being more accurate in the methodology, given the nature of the information, the researchers used a quasi-meta-analysis for processing the data. Half (50%) of the countries have similar causes of delay, and likewise, 50% of the countries identified the top ten primary causes of delay in road construction projects based on the intensity results. This study uses the results of the intensity. According to the results of the homologation, the lack of experience of the construction manager, inadequate planning/scheduling, and influence on people’s land alongside the road construction project (expropriation for the construction of the project) have more significant impacts than frequent changes in the design (which was listed as the most frequent cause of delay).
