The city governments promote the application of recycled aggregate but often faced with the lack of lateral communication between the engineering authority and the environmental protection authority. Insufficient information on the use of recycled aggregate among design units, construction units, manufacturing supervision units and material supply agencies have resulted in limited promotion results. In addition, the types of recycled aggregate are diverse, and the applicable engineering projects are overlapped. In terms of the management of recycled aggregate, recycled aggregate should be used appropriately to avoid the situation where various recycled aggregates are concentrated for the same purpose. This project assists New Taipei City to promote three pilot projects of recycled aggregate, to establish construction outline specifications, formulate relevant laws and regulations, through the guidance of production sources and recycling agencies to develop a verification system for recycled aggregate, and integrate the operation procedures promoted by the production source, reuse organization, and construction unit at various stages, as a promotion reference for other cities.
