Examining green road construction components: the case of Ghana

Purpose: The 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/approach: Using 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. Findings: The study's results reveal that the identified components: sustainable design, materials and resources, stormwater management and energy efficiency, significantly influence green road construction. Practical implications: It 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/value: Results from this study provide empirical evidence lacking in the literature about the main components of green road construction.
