Pavement paving filling type large-particle-size cement stabilized macadam base material and method
The invention relates to the technical field of road materials, in particular to a filling type large-particle-size cement stabilized macadam base material for pavement paving and a method. The filling type large-particle-size cement stabilized macadam base material is prepared from the following materials in parts by weight: 10-20 parts of cement; 10-20 parts of medium sand; 10-20 parts of fine sand; 60-80 parts of stones; 40-50 parts of slag; 20-30 parts of coal cinder; 20-30 parts of lime powder; and 10-20 parts of a glass fiber mesh. A preparation method of the filling type large-particle-size cement stabilized macadam base material for pavement paving comprises the following steps that S1, an old pavement is treated, foreign matter on the old pavement is cleared away, a road roller is adopted for rolling and flattening, and then watering and airing are conducted; s2, lime powder is spread, specifically, lime powder is spread on the old pavement treated in the S1, a road roller is adopted for rolling and flattening, and then water spraying treatment and air drying are conducted. The multiple layers of glass fiber nets are embedded in the concrete base layer during construction, so that the deformation resistance of the base layer is high, the bending and tensile strength is high, the cracking phenomenon of the pavement base layer can be effectively prevented, and the service life of a road is prolonged.
本发明涉及公路材料技术领域，具体是一种路面铺设填充式大粒径水泥稳定碎石基层材料及方法，包括以下重量份材料制成：水泥10‑20；中砂10‑20；细砂10‑20；石子60‑80；矿渣40‑50；煤渣20‑30；石灰粉20‑30；玻璃纤维网10‑20。一种路面铺设填充式大粒径水泥稳定碎石基层材料的制备方法，包括以下步骤：S1：处理旧路面，将旧路面上的异物清除干净，采用压路机碾压平整，然后洒水并晾干；S2：撒石灰粉，将S1中处理后的旧路面摊铺上石灰粉，采用压路机碾压平整，然后洒水处理并晾干。本发明利用多层的玻璃纤维网在施工时内嵌在混凝土的基层内部，使得基层的抗变形能力较大，抗弯拉强度较强，能够有效防止路面基层的开裂现象的发生，使得公路的使用寿命得到延长。
