Abstract

PurposeThe adoption of green construction concepts in road infrastructure projects is an opportunity to minimise the carbon footprint while boosting the built environment's capacity to promote sustainability. Consequently, this study examines the components of green road construction practices in developing countries such as Ghana.Design/methodology/approachUsing a quantitative research method, four hypothesised constructs identified from the review of relevant literature were tested. The views of 144 quantity surveyors, civil engineers and project managers within Ghana's three road agencies were elicited using a structured close-ended questionnaire. A confirmatory factor analysis (CFA) based on the structural equation model (SEM) was adopted in analysing the data obtained.FindingsThe study's results reveal that the identified components: sustainable design, materials and resources, stormwater management and energy efficiency, significantly influence green road construction.Practical implicationsIt reveals the critical elements of sustainable road design and construction, aiding organisations, construction companies and legislators in making informed choices on road design and construction.Originality/valueResults from this study provide empirical evidence lacking in the literature about the main components of green road construction.

考察绿色道路建设的组成部分:以加纳为例
目的在道路基础设施项目中采用绿色建筑理念是一个机会,可以最大限度地减少碳足迹,同时提高建筑环境的可持续性。因此,本研究考察了加纳等发展中国家绿色道路建设实践的组成部分。设计/方法学/方法采用定量研究方法,对从相关文献综述中确定的四个假设构念进行检验。加纳三家公路机构的144名工料测量师、土木工程师和项目经理的意见是通过结构化封闭式问卷调查得出的。采用基于结构方程模型(SEM)的验证性因子分析(CFA)对所得数据进行分析。研究结果表明,可持续设计、材料和资源、雨水管理和能源效率等要素对绿色道路建设有显著影响。它揭示了可持续道路设计和建设的关键要素,帮助组织、建筑公司和立法者在道路设计和建设方面做出明智的选择。独创性/价值本研究的结果提供了文献中缺乏的关于绿色道路建设主要组成部分的经验证据。
