Special grouting material for rut-resistant composite pavement and preparation method of special grouting material
The invention discloses an anti-rut composite grouting material special for a pavement and a preparation method thereof. The anti-rut composite grouting material comprises ordinary Portland cement, fly ash, glass beads, aromatic oil, a water reducing agent, a retarder, redispersible latex powder, a water-retaining agent, a defoaming agent, an expanding agent, cellulose ether and water glass. The preparation method comprises the following steps: mixing the ordinary Portland cement, the fly ash, the glass beads, the cellulose ether, the water reducing agent, the retarder, the redispersible latex powder and the expanding agent to prepare a first mixture; mixing the aromatic hydrocarbon oil, the water-retaining agent, the defoaming agent and the water glass to obtain a second mixture, and independently packaging the first mixture and the second mixture to obtain the grouting material. The grouting material has excellent fluidity and small shrinkage deformation under the condition of ensuring a reasonable water cement ratio, the volume stability of the grouting material is improved, the cracking risk of the grouting material is reduced, and the rutting resistance of a pavement prepared from the grouting material is further improved; and meanwhile, the preparation process of the grouting material is convenient and high in operability.
本发明公开了一种抗车辙复合型路面专用灌浆料及其制备方法，包括普通硅酸盐水泥、粉煤灰、玻璃微珠、芳烃油、减水剂、缓凝剂、可再分散乳胶粉、保水剂、消泡剂、膨胀剂、纤维素醚及水玻璃；制备时将普通硅酸盐水泥、粉煤灰、玻璃微珠、纤维素醚、减水剂、缓凝剂、可再分散乳胶粉、膨胀剂混合后，制得第一混合料；将芳烃油、保水剂、消泡剂及水玻璃混合后，制得第二混合料，第一混合料和第二混合料独立封装，制得该灌浆料。该灌浆料能够在确保合理的水灰比条件下，具有优异的流动性和小收缩变形量，改善了灌浆料的体积稳定性，降低了灌浆料的开裂风险，进而提高了采用该灌浆料制备的路面的抗车辙性；同时，该灌浆料的制备工艺便捷，可操作性强。
