The invention discloses a special curing agent for red-mud-based gold tailing roadbeds as well as a preparation method and a use method of the curing agent, belongs to the field of road engineering and aims to solve the technical problems of how to effectively reduce pollution of gold tailings, improve long-term stability of gold tailing roadbeds, apply the gold tailings to road construction on a large scale, turn waste into wealth and save non-renewable land resources. The technical scheme is as follows: the curing agent is mainly prepared from raw materials through mixing in parts by weight as follows:50-60 parts of cement, 20-35 parts of red mud, 10-25 parts of a modifier and 1-5 parts of a stabilizer. With the adoption of the use method of the curing agent, the curing agent is added to the gold tailings, a roadbed mixture is obtained after uniform evening and used for roadbed paving, and the mass percentage of the curing agent in the roadbed mixture is 8%-12%. 本发明公开了赤泥基黄金尾矿路基专用固化剂及其制备方法和应用方法，属于道路工程领域，本发明要
