Utilization of Sensors in Monitoring the Quality of Sustainable Asphalt

The quality of road infrastructure, particularly asphalt, is crucial in urban and transportation development, as high-quality asphalt enhances user comfort, safety, and cost-efficient maintenance while supporting environmental sustainability. However, 31.91% of roads in Indonesia are damaged, highlighting the need for effective monitoring systems. This study evaluates sensor technology for sustainable asphalt quality monitoring and explores strategies for its integration into infrastructure management. While prior research has focused on technical aspects, challenges in data integration and high implementation costs remain unaddressed. A systematic literature review was conducted using Scopus, Google Scholar, and IEEE Xplore, analyzing studies from the past five years based on sensor types, applications, and implementation challenges. Findings show that sensors provide real-time data on temperature, moisture, and pressure, reducing maintenance costs by 25-30% through early detection. Intelligent compaction and structural health monitoring systems improve long-term road performance. However, high initial costs, lack of standardization, and difficulties in integrating multi-sensor data hinder widespread adoption. Addressing cost barriers and ensuring seamless integration with infrastructure management are crucial, with future research needed to develop cost-effective and interoperable sensor solutions.
