High modulus modifier blend of asphalt mixture
The invention relates to an organic-inorganic composite material for asphalt mixture modification, in particular to a high-modulus modifier blend of an asphalt mixture, the high-modulus modifier blendis composed of modified calcium sulfate whiskers and polyolefin, and the mass ratio of the modified calcium sulfate whiskers to the polyolefin is 20-80: 20-80. The high-modulus modifier blend is usedin an asphalt mixture, can significantly improve the rutting resistance of the asphalt mixture, can also improve the water stability and low-temperature crack resistance of the asphalt mixture, and also has the advantages of easily available raw materials, low price and the like.
本发明涉及一种沥青混合料改性用有机‑无机复合材料，具体为一种沥青混合料的高模量改性剂共混物，所述所述高模量改性剂共混物由改性硫酸钙晶须和聚烯烃组成，且所述改性硫酸钙晶和所述聚烯烃的质量比为20～80:20～80。本发明所述的高模量改性剂共混物用于沥青混合料中，可显著提高沥青混合料的抗车辙性能，也能提高沥青混合料的水稳定性及低温抗裂性能，且还具有原料易得和价格低廉等优点。
