The invention provides a steel slag asphalt concrete with good thermal stability and water stability. The steel slag asphalt concrete with good thermal stability and water stability comprises the following components in percentage by weight: 4% of asphalt oil raw material; 82% of a steel slag raw material; 0.5% of a heat stabilizer; 0.4% of a water stabilizer; 4.2% of a high thermal conductivity filler; and balance of water. The steel slag asphalt concrete with good thermal stability and water stability provided by the invention has the advantages that the water stabilizer is added into a mixture of the steel slag asphalt concrete; the rut resistance, the low-temperature crack resistance, the water stability and the fatigue resistance of the steel slag asphalt mixture are improved; the effects are increased, according to the steel slag asphalt concrete, the heat stability of the whole steel slag asphalt concrete is greatly improved, the interior of the steel slag asphalt concrete stillhas good stability when the external temperature changes greatly, the phenomena that the steel slag asphalt concrete is prone to aging and cracking due to temperature difference changes are effectively avoided, the service life of the steel slag concrete is prolonged, and the environmental adaptability is improved.
本发明提供一种热稳定性和水稳定性好的钢渣沥青混凝土。所述热稳定性和水稳定性好的钢渣沥青混凝土包括如下重量百分比的组分：沥青油原料4％；钢渣原料82％；热稳定剂0.5％；水稳定剂0.4％；高导热填料4.2％；其余为水。本发明提供的热稳定性和水稳定性好的钢渣沥青混凝土具有通过水稳定剂添加至钢渣沥青混凝土的混合料中，具有提高钢渣沥青混合料抗车辙性能、低温抗裂性、水稳定性和抗疲劳性能，提高效果显著，使钢渣沥青混凝土整体的热稳定大大提高，在外界温度变化较大时，钢渣沥青混凝土的内部仍具有良好的稳定性，有效的避免温差的变化导致钢渣沥青混凝土易发生老化和开裂的现象，延长钢渣混凝土的使用寿命和环境适应力。
