To expand the application range and usage of recycled aggregate in public construction projects, this project aims to decrease the stakeholders’ concern about its characteristic and products performance. Stakeholders including engineering units, environmental protection units, experts, researchers, as well as mass. For improving user’s knowledge of recycling aggregates’ characteristics and performance, this project organized seven domestic conferences to pass on experience in real construction cases, including crucial issues and design points. Notices and design points were consolidated as reference for potential users. This project also held two observation and learning activities to observe the recycled aggregate manufacturing process and application results. Attempt to propose multiple refinements, the recycled aggregate application crucial problems such as supply chain and utilization situation were discussed. Finally, the improvement recommendations had been advised from participating stakeholders in 3 expert meetings.
