Rolling-free self-compacting ardealite base road construction method
The invention provides a rolling-free self-compacting ardealite base road construction method, and belongs to the field of road construction. According to the construction technology, the characteristics of phosphogypsum components are combined, mineral powder is selected as a main active cementing material, cement is selected as an alkali activator, a small amount of phosphogypsum is selected as a sulfate activator, a composite modified cementing material is formed, the mass ratio of phosphogypsum to broken stone to machine-made sand to cement to slag to water to an additive is controlled to be 21.03: 17.52: 4.30: 1.0: 2.73: 6.97: 0.14, all the components are subjected to forced centrifugal mixing, and the composite modified cementing material is prepared. The ardealite base material which is in a flow plastic state, is fully hydrated, is uniform and compact and is applied to a base road, the result shows that the technology has the characteristics of reliable performance, simple process and relatively good economical efficiency, the effects of quickly consuming the ardealite and reducing the stock stacking pressure are achieved, the effects of resource utilization and turning waste into treasure are achieved, and the ardealite base material can be applied to a base road. And the method has remarkable economic benefits and social benefits, and can be popularized and applied to road bases of municipal and highway engineering.
本发明提供了一种免碾压的自密实磷石膏基层道路施工方法，属于道路施工领域。本发明的施工技术结合磷石膏组分特性，选用矿粉作为主要活性胶凝材料，水泥作为碱激发剂、少量磷石膏作为硫酸盐激发剂，形成复合改性胶凝材料，通过控制磷石膏、碎石、机制砂、水泥、矿渣、水和外加剂的质量比为21.03:17.52:4.30:1.0:2.73:6.97:0.14，让各组分经强制离心拌和，形成一种流塑态、充分水化、均匀致密的磷石膏基层材料，并将该材料应用于基层道路中，结果显示，该技术具有性能可靠、工艺简单、经济性较好的特点，不仅起到快速消耗磷石膏,降低库存堆放压力的作用，达到资源化利用、转废为宝的效果，而且具有显著的经济效益和社会效益，可推广应用于市政、公路工程的道路基层中。
