技術簡介
為落實政府資源循環與淨零轉型政策,以道路鋪面材料循環利用及延長道路生命週期為核心,建立刨除料全循環應用策略:一是直接再生,透過工研院瀝青再生劑恢復老化瀝青性能,使刨除料部分回用於道路面層,兼顧循環材料使用與鋪面品質;二是分離再利用,運用刨除料瀝青砂石分離技術,將老化瀝青與骨材分離並還原為再生石與瀝青砂,使材料可100%重回道路鋪面材料應用;三是鋪面延壽,導入抗車轍之長效循環鋪面,以鋼質粒料、刨除料等多元循環材料取代天然粒料,兼具資源循環與道路延壽效益;四是減量維護,開發道路預防性維護技術,於鋪面劣化初期即進行修復,延緩全面刨鋪時程,降低刨除料產生及材料消耗。透過「循環使用、全數再生、道路延壽、預防維護」四項策略,推動道路鋪面材料由線性消耗邁向全循環應用。
Abstract
(英文)
To support the government’s resource circulation and net-zero transition policies, this technology focuses on promoting the circular use of pavement materials and extending pavement service life through a comprehensive recycling strategy for Reclaimed Asphalt Pavement (RAP). First, direct recycling: ITRI’s asphalt rejuvenator is used to restore the properties of aged asphalt, enabling partial reuse of RAP in surface courses while maintaining pavement quality. Second, separation and recycling: ITRI’s asphalt–aggregate separation technology separates aged asphalt from aggregates and recovers RAP into recycled aggregate andasphalt-rich fine material, allowing 100% of the materials to be reused in pavement applications. Third, pavement life extension: rut-resistant, long-life circular pavement technology incorporates multiple recycled materials, such as steel-derived aggregates and RAP, to replace natural aggregates, achieving both resource circulation and longer pavement service life. Fourth, reduced-maintenance demand: preventive pavement maintenance technologies are applied at the early stage of pavement deterioration to delay full-depth milling and resurfacing, thereby reducing RAP generation and material consumption. Through the four strategies ofcircular reuse, full-material recycling, pavement life extension, and preventive maintenance, pavement materials can transition from a linear consumption model toward a fully circular application system.
