Cement-emulsified semi-flexible high-strength asphalt concrete micro-expansive agent and preparation method thereof
The invention discloses a cement-emulsified semi-flexible high-strength asphalt concrete micro-expansive agent and a preparation method thereof.The prepared micro-expansive agent can effectively control the performance of asphalt and asphalt concrete, a component A can effectively control the ductility and viscosity of the asphalt, the ductility and viscosity can be controlled between 200 mm and 1000 mm at the temperature of 10 DEG C, and the viscosity can be controlled between 200 mm and 1000 mm at the temperature of 10 DEG C; the low-temperature crack resistance of the asphalt concrete is effectively improved, the coating property with the coarse aggregate is better, the coating area is greater than or equal to 4/5, and the water stability of the cold-recycled mixture can be obviously improved; the component B achieves the purpose of micro-expansion, the porosity of the asphalt concrete is reduced, the porosity can be controlled within 8-13%, the water damage resistance of the asphalt concrete is further improved, and the strength of the asphalt concrete is improved; meanwhile, the component C can regulate and control the demulsification time of the emulsified asphalt, the demulsification speed can be controlled within 3-8 h, and the mixing and construction requirements are completely met.
本发明公开了一种水泥‑乳化半柔性高强沥青混凝土微膨胀剂及其制备方法，本发明所制备的微膨胀剂可有效控制沥青和沥青混凝土的性能，其中A组份可有效控制沥青的延度和粘度，10℃时可控制在200～1000mm之间，有效提高沥青混凝土的低温抗裂性，与粗集料的裹覆性较好，裹覆面积≥4/5，可显著提高冷再生混合料的水稳定性能；B组份起到微膨胀的目的，减少沥青混凝土的孔隙率，孔隙率可控制在8～13％内，进一步提高沥青混凝土的抗水损害性能，提高沥青混凝土的强度；同时C组份能调控乳化沥青的破乳时间，破乳速度可控制在3‑8h，完全满足拌合与施工要求。
