Towards Sustainable Road Construction: Literature Review on Addressing Environmental Impacts and Promoting Green Technologies

Abstract This study investigates the environmental impacts of road construction and explores strategies to promote green technologies in Indonesia. Traditional road construction methods, particularly those using asphalt and cement, have significant energy consumption and greenhouse gas emissions. This study conducted a thorough literature review to investigate green technologies and best practices to reduce emissions during the construction process. The literature review included articles published from 2004 to 2024, drawn from various national and international academic sources, and adopted the PRISMA method. It was found that key strategies include recycled materials, warm mix asphalt technology, permeable pavement systems, green roofs, and energy-efficient equipment. To mitigate these impacts, the study recommends using recycled materials, adopting energy-efficient technologies, implementing sustainable design practices, and conducting life cycle assessments. Although Indonesia has made progress, challenges such as limited funding, technology, and coordination remain. Overcoming these challenges requires increased commitment and funding, capacity building, better coordination, and stricter regulations. Future studies should investigate the development and implementation of innovative green technologies, including advanced recycled materials, more efficient construction equipment, and innovative pavement design techniques.
