Semi-flexible pavement cement-based adhesive cement composition and preparation method thereof

The invention provides a semi-flexible pavement cement-based adhesive cement composition and a preparation method thereof, and belongs to the technical field of pavement materials, the semi-flexible pavement cement-based adhesive cement composition is prepared from the following raw materials by weight: 100-120 parts of cement, 20-30 parts of inorganic nano hollow particles, 5-30 parts of quartz sand, 1-5 parts of a polymer emulsion, 0.1-1 part of a thixotropic agent, 0.1-2 parts of an antifoaming agent, 0.1-0.7 part of an expanding agent and 150-200 parts of water; the particle size of the quartz sand is 0.5-2 mm; and the cement is 42.5 sulphoaluminate cement. The semi-flexible pavement cement-based adhesive cement disclosed by the invention is good in fluidity, good in rheological property of a whole system, relatively good in mechanical property, good in high-temperature rutting resistance, low-temperature cracking resistance, water damage resistance and fatigue resistance, and capable of prolonging the se
