High-thermal-stability cement asphalt mortar and preparation method thereof
The invention discloses high-thermal-stability cement asphalt mortar and a preparation method thereof, and relates to the technical field of preparation of cement asphalt mortar. The mortar is prepared from the following components: 1200 to 1300 g of dry powder, 600 to 630 g of emulsified asphalt, 70 to 80 g of water, 2 to 2.3 g of a de-foaming agent, 0.05 to 0.1 g of aluminum powder and 1.24 to 3.72 g of carbon nano tubes. According to the high-thermal-stability cement asphalt mortar, the deformation resistance of asphalt is improved, and the temperature sensitivity of movement of a macromolecular chain segment of the asphalt is reduced, so that the overall deformation temperature stability of the cement emulsified asphalt mortar is improved, and the serious safety problem caused by insufficient deformation temperature stability of a plate type ballastless track can be solved; and the service life of an engineering structure with insufficient deformation temperature stability can be effectively prolonged. The problem that existing mortar is low in deformation temperature stability is solved.
本发明公开了一种高热稳定性水泥沥青砂浆及其制备方法，涉及水泥沥青砂浆制备技术领域。该砂浆包括以下组分：干粉1200‑1300g、乳化沥青600‑‑630g、水70‑80g、消泡剂2‑2.3g、铝粉0.05‑0.1g和碳纳米管1.24‑3.72g。本发明的高热稳定性水泥沥青砂浆提高了沥青的抗变形能力，降低了沥青高分子链段运动的温度敏感性，从而提高了水泥乳化沥青砂浆整体的变形温度稳定性，可解决板式无砟轨道由于变形温度稳定性不足，而暴露出的严重安全性问题，可有效提高变形温度稳定性不足的工程结构的服役寿命。本发明解决了现有砂浆变形温度稳定性低的问题。
