Early-strength semi-flexible pavement grouting material as well as preparation method and application thereof
The invention discloses an early-strength semi-flexible pavement grouting material as well as a preparation method and application thereof. The early strength type semi-flexible pavement grouting material is prepared from the following components in parts by weight: 55 parts of ordinary Portland cement, 10 to 15 parts of fly ash, 10 to 15 parts of river sand, 1 to 5 parts of a water reducing agent, 1 to 5 parts of nano silicon dioxide, 1 to 5 parts of modified cellulose, 1 to 5 parts of sorbitan monooleate and 45 to 55 parts of water. The mortar has the advantages of early strength, rapid hardening and high fluidity, has high viscosity and low dry shrinkage rate, effectively avoids the occurrence of diseases such as deformation of a semi-flexible pavement, meets the technical requirements of the China Engineering Construction Standard Association Standard Urban Road Grouting Semi-Flexible Pavement Technical Regulations (T/CECS 1016-2022), can be seamlessly bonded with an asphalt mixture matrix, and has the advantages of high strength, high hardness and high fluidity. No obvious shrinkage phenomenon exists after hardening, and the actual application effect is good.
本发明公开了一种早强型半柔性路面灌浆料及其制备方法与应用。该早强型半柔性路面灌浆料，按重量份数计，包括以下组分：普通硅酸盐水泥55份、粉煤灰10‑15份、河砂10‑15份、减水剂1‑5份、纳米二氧化硅1‑5份、改性纤维素1‑5份、山梨醇酐单油酸酯1‑5份，以及水45‑55份。兼具早强快硬和高流动度的优点，并具有高粘的性能，干缩率低，有效地避免半柔性路面变形等病害发生，符合中国工程建设标准化协会标准《城市道路灌浆式半柔性路面技术规程》(T/CECS 1016‑2022)技术要求，能够与沥青混合料基体间可以无缝粘结，硬化后无明显收缩现象，实际应用效果良好。
