SAP-doped shrinkage-reducing anti-cracking cement stabilized macadam and preparation method thereof
The invention relates to the technical field of road engineering materials, and provides SAP-doped shrinkage-reducing anti-cracking cement stabilized macadam and a preparation method thereof. The SAP-doped shrinkage-reducing anti-cracking cement stabilized macadam comprises the following components in parts by weight: 100 parts of macadam, 5 parts of cement, 5-6 parts of water and 0.01-0.03 part of sodium polyacrylate, the sodium polyacrylate comprises first sodium polyacrylate and second sodium polyacrylate, the particle size of the first sodium polyacrylate is 30-80 meshes, the particle size of the second sodium polyacrylate is 90-150 meshes, and the mass of the first sodium polyacrylate is smaller than that of the second sodium polyacrylate. According to the technical scheme, the problem that a cement stabilized macadam base is prone to shrinkage and cracking in the prior art is solved.
本发明涉及道路工程材料技术领域，提出了一种掺SAP的减缩抗裂水泥稳定碎石及制备方法。掺SAP的减缩抗裂水泥稳定碎石，包括以下重量份的组分：碎石100份，水泥5份，水5~6份，聚丙烯酸钠0.01~0.03份；聚丙烯酸钠包括第一聚丙烯酸钠和第二聚丙烯酸钠，第一聚丙烯酸钠的粒径为30~80目，第二聚丙烯酸钠的粒径为90~150目，第一聚丙烯酸钠的质量＜第二聚丙烯酸钠的质量。通过上述技术方案，解决了相关技术中水泥稳定碎石基层易收缩开裂的问题。
