At the end of the project, the site pavement needs to be broken up, which wastes manpower and financial resources, generates a large amount of construction waste, and increases environmental pollution. Therefore, prefabricated temporary road slabs came into being.

[0003] However, due to the lack of foundation stability of soft soil roadbed, it may not provide sufficient support in the vertical direction; lack of sufficient stability in the lateral direction, the roadbed is very likely to settle or deform, resulting in uneven load distribution of existing temporary road slabs, which in turn affects their performance and stability; therefore, existing prefabricated road slabs are not suitable for special soft soil areas. To this end, we provide a prefabricated, recyclable, high-performance multi-rib prestressed prefabricated road slab suitable for use in soft soil roadbed areas. Utility Model Content
