【摘要】：鋼渣是一種工業(yè)副產(chǎn)品,常被當(dāng)成廢棄物而隨意處理,但其具有耐磨、抗滑、高堿性等特征,與瀝青間粘附性較好,可以作為集料使用。研究了鋼渣原材料性能、鋼渣透水瀝青混合料設(shè)計(jì)、路用性能。研究表明:鋼渣具有耐磨、抗滑、高堿性等特征;鋼渣透水瀝青混凝土配合比設(shè)計(jì)時(shí),傾向于采用鋼渣粗集料與天然細(xì)集料復(fù)配的方案,并采用SBS改性瀝青和纖維穩(wěn)定劑增強(qiáng)其穩(wěn)定性和耐久性;利用鋼渣制備透水瀝青混凝土具有良好的高溫穩(wěn)定性、優(yōu)異的水穩(wěn)定性,鋼渣透水路面滲水和抗滑性能完全滿足規(guī)范要求。該研究推動(dòng)了鋼渣透水瀝青混凝土的發(fā)展,促進(jìn)了鋼渣在道路建設(shè)中的廣泛應(yīng)用。
[Abstract]:Steel slag is a kind of industrial by-product, which is often treated as waste at will, but it has the characteristics of wear resistance, skid resistance, high alkalinity and good adhesion with asphalt, so it can be used as aggregate. The raw material performance of steel slag, the design of steel slag permeable asphalt mixture and the road performance were studied. The results show that steel slag has the characteristics of wear resistance, skid resistance and high alkalinity. In the mix proportion design of steel slag permeable asphalt concrete, it tends to adopt the combination scheme of steel slag coarse aggregate and natural fine aggregate, and SBS modified asphalt and fiber stabilizer are used to enhance its stability and durability. The preparation of permeable asphalt concrete from steel slag has good high temperature stability and excellent water stability. The seepage and skid resistance of steel slag permeable pavement fully meet the requirements of the code. This study promotes the development of steel slag permeable asphalt concrete and promotes the wide application of steel slag in road construction.
