Environmental sustainability issues have been incorporated into product development in recent years. The design stage is key to integrating these issues, so the EcoDesign (ED) strategies were developed in the manufacturing industry to direct sustainable product design. Construction projects have also been requested to incorporate sustainability but most of them are green buildings. Other types of construction projects need strategies or tools to facilitate sustainability incorporation.
This study developed ED strategies for roadway projects. First, sixty sustainability design items in 14 disciplines for roadway design were identified. Then, the manufacturing ED strategies were referenced and adjusted into eight applicable strategies for construction projects. The 60 items were linked with the eight ED strategies through interviewing designers. The results showed that the two ED strategies of “reduction in weight/volume” and “reduction of impact during use” were more adopted by roadway projects with 34% and 33%, respectively; the 14 design disciplines adopted the eight ED strategies with different proportions. The findings indicate the direction leading roadway projects towards sustainability and reducing trial and error by designers.
