Polypropylene fiber modified cement stabilized macadam and preparation method thereof
The invention relates to polypropylene fiber modified cement stabilized macadam, which is prepared from the following components in parts by weight: 95 to 105 parts of aggregate, 4.0 to 4.5 parts of Portland cement, 0.01 to 0.18 part of modified polypropylene fiber, and 3.5-4.0 parts of water. The invention also provides a preparation method of the polypropylene fiber modified cement stabilized macadam. The modified polypropylene fiber is added to modify the cement stabilized macadam, so that the durability problem of the existing semi-rigid base is solved, the shrinkage cracking resistance, the tensile strain resistance and the deformation resistance of the semi-rigid base are improved, and the cement stabilized macadam material can be well prevented from cracking due to temperature and drying shrinkage obstruction.
本发明涉及一种聚丙烯纤维改性水泥稳定碎石，包括如下重量份的组分：骨料95‑105份；硅酸盐水泥4.0‑4.5份；改性聚丙烯纤维0.01‑0.18份；水3.5‑4.0份。本发明还提供一种聚丙烯纤维改性水泥稳定碎石的制备方法。本发明通过添加改性聚丙烯纤维改性水泥稳定碎石，解决了目前半刚性基层存在的耐久性问题，提高其抗收缩开裂能力、抗拉应变能力和抗变形能力，能够很好地的阻止水泥稳定碎石材料因温度和干燥收缩受阻而开裂。
