Circular Economy Practices in Pavement Management System
摘要
The EU aims to accelerate the transition to a circular economy to reduce waste and its environmental impact since the linear economy model imposes significant environmental burdens. Resources are finite, and the consequences of environmental degradation, climate change, and disaster risks cannot be ignored. The construction industry accounts for over 38% of waste in Europe, so it has become inevitable to activate road maintenance as one of the enablers for the transition towards circular economy strategies. This study aims to explore circular economy (CE) frameworks, indicators, and sustainable maintenance and rehabilitation (M&R) materials and methods. For this purpose, a systematic review has been conducted to explore the transition towards the circular economy and its interconnectivity with the road Pavement Management System (PMS). Scopus and Web of Science (WoS) are the primary databases that have been explored. Google Scholar also has been explored to complete the references. By examining and analyzing 62 papers from the mentioned databases, 26 relevant papers have been selected. By examining the previous practices of CE implementation, the review highlights how pavement maintenance of road have evolved to become more circular. This study highlights different CE frameworks, indicators, and sustainable maintenance materials, methods, and technologies that can facilitate circular PMS practices.
