Life Cycle Cost (LCC) analysis is a method introduced to highlight the return of investment and cost risks that possibly encounter during the life span of the buildings or infrastructures. Besides green building, "green highway" or "green road" is among the emerging concern in sustainable construction. The establishment of Green Highway & Road (H&R) Rating Tools such as Malaysia Green Highway Index (MyGHI), offers multi-criteria of sustainable initiatives that count towards the score of the green certification of H&R. This paper aims to establish relationship of life cycle costing components to the green highway projects using the highways certified by MyGHI to identify relationships between LCC components and the green highway’s criteria cost. A questionnaire survey of 65 respondents was conducted. Friedman's Test and Spearman's Correlation Coefficient Analysis were used to validate LCC component and establish the relationship. Then PLS-SEM was used to validate the correlation coefficient of cost component towards total LCC of green criteria. Results show that the energy efficiency green criteria cost have a positive and significant relationship except for capital, maintenance, and replacement costs. This study innovation is novel in terms of an alternative for reducing the negative perception of green highways and exceptionally facilitates decision-making, hence, aiding the H&R stakeholders in foreseeing the green highway cost benefits. © 2023, Construction Research Institute of Malaysia.
