研究期間:10106~10205;The traditional hot-mix asphalt concrete energy consumption and greenhouse gas emissions have been concerned because the rising of the international energy and oil price, and global carbon reduction consensus. The Executive Yuan also set the short-term carbon-reducing goal in 2020, as much as in 2005. promoting the "Energy-saving and Carbon-reducing Year", therefore, in response to global climate change and focus on energy saving, there are many research in the technique of warm-mix asphalt Concrete in domestic and foreign. In addition, the land and the resources are limited, and the gravel mining in the river is illegal, the sandstone shortage has became a serious problem in Taiwan, the Sand and gravel effective reuse is increasingly important. Based on the resource reuse and the environmental protection, the reuse of RAP (Reclaimed Asphalt Pavement) is necessary. Taiwan is located in the subtropical regions, where is high-temperatur and rainfall-abundant in summer. That is, rain is liable to infiltrate into the asphalt concrete via asphalt pores or cracks, making the concrete peel off or failure by fatigue. The performance against moisture of warm-mix asphalt concrete is worse than that of traditional hot-mix one. The main purpose of this study is to combine the asphalt concrete with warm-mix asphalt concrete, to use Marshall mix design method to product test body, to conduct laboratory effectiveness tests and field test, and to explore the benefits of energy saving and carbon reduction and feasibility assessment of the warm-mix asphalt concrete used in the subtropical regions.
