摘要:

道路建筑材料的生態(tài)設計是將材料的環(huán)境負荷、使用性能和經(jīng)濟成本綜合考慮到材料設計過程之中，以生命周期評價（LCA，Life Cycle Assessment) 思想為指導，使用生態(tài)化改造設計開發(fā)與環(huán)境相協(xié)調(diào)的材料。本研究以天然石料瀝青混凝土道路面層為參考基準，通過確定產(chǎn)品設計目標，需求分析，實施設計以及評價等步驟進行鋼渣瀝青混凝土道路面層的生態(tài)設計。結果表明：鋼渣瀝青混凝土的全生命周期環(huán)境負荷比天然石料瀝青混凝土約低14.17%，使用性能比其高出31.87%，建設1km道路所需經(jīng)濟成本比其低8.37%，且生態(tài)設計綜合評價結果也優(yōu)于天然石料瀝青混凝土。因此，鋼渣瀝青混凝土在環(huán)境負荷、使用性能、經(jīng)濟成本和綜合表現(xiàn)上均要優(yōu)于天然石料瀝青混凝土，即鋼渣瀝青混凝土路面比天然石料瀝青混凝土路面更符合生態(tài)設計要求，為道路建筑材料的綠色設計和選材提供了依據(jù)。

Abstract:

The Eco-design of road building material is that the environmental load, performance and economic cost of the material will be considered into the material design process, with the idea of life cycle assessment as a guide, through the ecological reconstruction can make the materials in harmony with the environment. This study conducted an Eco-design of steel slag asphalt concrete road surface through the steps include the determination of product design objectives, needs analysis, design implement and evaluation with the natural stone asphalt concrete as a reference. The results show that the life cycle environment load of the steel slag asphalt concrete is about 14.17% lower than natural stone asphalt concrete and 31.87% higher than its using performance, the economic cost of 1 km road construction is 8.37% lower than the steel slag asphalt concrete required, the Eco-design comprehensive evaluation result is greater than natural stone asphalt concrete, so the steel slag asphalt concrete are better than natural stone asphalt concrete in the environmental load, using performance, economic cost and overall performance，we can get a conclusion that the steel slag asphalt concrete pavement is more in line with the Eco-design the requirements than natural stone asphalt concrete pavement, which provide the basis for the green design and selection of road building materials.
