Preparation method of retarded cement stabilized macadam and paving method of base layer of retarded cement stabilized macadam
The invention relates to the technical field of cement stabilized macadam, and provides a preparation method of retarded cement stabilized macadam, which comprises the following steps: mixing and stirring cement, ardealite, epoxy methylsiloxane, polyacrylamide and graded stone according to the weight ratio of (4-6): (5-10): (1-3): (2-3): (77-88) to obtain a dry material; adding 3-7 parts by weight of water into the dry material, and stirring to obtain the retarded cement stabilized macadam; the base layer paving method comprises the following steps: construction preparation; blending the retarded cement stabilized macadam; transporting the retarded cement stabilized macadam; paving a delayed coagulation cement stabilized macadam base layer; compacting the delayed coagulation stabilized macadam base layer; performing joint treatment; after continuous pressing is completed, emulsified asphalt can be directly sprayed for curing, geotechnical cloth can also be adopted for covering and watering for curing, and the curing time is not less than 7 days. The invention has the advantages of green industrial waste and high added value utilization, and can shorten the construction period of the pavement base layer and guarantee the integrity of the structural layer, thereby prolonging the service life of the pavement and reducing the maintenance cost.
本发明涉及水泥稳定碎石技术领域，提供了一种缓凝水泥稳定碎石的制备方法，水泥、磷石膏、环氧基甲基硅氧烷、聚丙烯酰胺与级配石料按照重量比4~6份：5~10份：1~3份：2~3份：77~88份混合并搅拌，获得干料；干料内加3~7重量份水搅拌，获得缓凝水泥稳定碎石；基层铺施方法，采用以下步骤，施工准备；缓凝水泥稳定碎石拌合；缓凝水泥稳定碎石运输；摊铺缓凝水泥稳定碎石基层；压实缓凝稳定碎石基层；接缝处理；连压完成后，可直接洒布透乳化沥青养生，也可采用土工布覆盖洒水养生，养生时间不少于7d。本发明具有工业废弃物绿色、高附加值利用优势，并可缩短路面基层施工周期、保障结构层整体性，从而延长路面寿命、降低养护成本优势。
