Low-carbon high-performance modified asphalt, asphalt concrete and preparation method thereof
The invention discloses low-carbon high-performance modified asphalt, asphalt concrete and a preparation method thereof, and relates to the technical field of preparation of asphalt for road engineering. The low-carbon high-performance modified asphalt takes camellia oleifera shell powder prepared from waste camellia oleifera shells as a raw material as an asphalt modifier, and the addition amount of the camellia oleifera shell powder is 4-16wt% of matrix asphalt. The modified asphalt modified by the camellia oleifera shell powder has excellent high-temperature performance and creep resistance. The asphalt modification method disclosed by the invention is simple in preparation process, relatively low in energy consumption and relatively low in application cost. According to the method, the resource comprehensive utilization of the waste camellia oleifera shells can be realized, waste is turned into wealth, the added value of the waste camellia oleifera shells is improved, the environmental problem caused by incineration of the waste camellia oleifera shells is solved, and the comprehensive performance of common petroleum asphalt can be greatly improved.
本发明公开一种低碳高性能改性沥青与沥青混凝土及其制备方法，涉及道路工程用沥青制备技术领域。所述低碳高性能改性沥青以废弃油茶壳为原料制得的油茶壳粉作为沥青改性剂，所述油茶壳粉的添加量为基质沥青的4～16wt％。经油茶壳粉改性后的改性沥青具有优良高温性能和抗蠕变性能。本发明的沥青改性方法制备工艺简单，能耗较低，应用成本较低。本发明不仅能实现废弃油茶壳的资源化综合利用，变废为宝，提高废弃油茶壳的附加价值，解决废旧油茶壳因焚烧带来的环境问题，而且还能大幅改善普通石油沥青的综合性能。
