Solid waste utilization calcium carbide dust and fly ash stabilized soil pavement structure and construction method
The invention discloses a solid waste utilization calcium carbide dust and fly ash stabilized soil pavement structure and a construction method, and relates to the technical field of road engineering. The calcium carbide dust and fly ash stabilized soil pavement structure utilizing the solid waste comprises an upper surface layer, a lower surface layer, a base layer, a subbase layer, a roadbed, calcium carbide dust, fly ash and coarse aggregate, and the upper surface layer is fine-grained asphalt concrete and is formed by mixing modified asphalt, gravel with small particle size, gravel and wood fiber according to a certain mixing ratio. According to the calcium carbide dust and fly ash stabilized soil pavement structure utilizing the solid waste and the construction method, by using the upper surface layer, the lower surface layer, the base layer, the subbase layer, the roadbed, the calcium carbide dust, the fly ash and the coarse aggregate, chemical solid waste recycling is achieved, the calcium carbide dust and fly ash stabilized soil pavement with the high strength stable value is provided, and the mode is energy-saving, environmentally friendly and free of environment pollution; the strength of the formed pavement structure is almost the same as that of lime and fly ash stabilized soil, and the pavement structure is suitable for base course and subbase course pavement structures of various high-grade roads.
本发明公开了一种固废利用电石灰粉煤灰稳定土路面结构及施工方法，涉及道路工程技术领域。该固废利用电石灰粉煤灰稳定土路面结构，包括上面层、下面层、基层、底基层、路床、电石灰、粉煤灰、粗骨料，所述上面层为细粒式沥青砼，由改性沥青、粒径较小的碎石、砂砾及木纤维按一定配合比混合组成。该固废利用电石灰粉煤灰稳定土路面结构及施工方法，通过使用上面层、下面层、基层、底基层、路床、电石灰、粉煤灰、粗骨料，实现化工固体废料再利用，提供强度稳定值较高的电石灰粉煤灰稳定土路面，该方式节能环保，不污染环境，实现化工废料再次利用，形成的路面结构强度几乎与石灰粉煤灰稳定土一样，适合各种高等级道路的基层与底基层路面结构。
