【Haichuan Chemical Construction Technology】Slag subgrade and all-steel pavement technology. During the construction process, a large amount of materials need to be delivered to the site, and heavy-duty transport vehicles are commonly used for their transportation. Material supply thus becomes a key factor determining the overall project timeline. Ensuring the smooth operation of material access roads is essential for maintaining a steady supply of materials, and it is of top priority; therefore, it is necessary to construct suitable construction access roads in order to guarantee material supply and the smooth progress of the project. The construction waste subgrade and all-steel pavement technology refers to a pavement made of construction waste composite slabs and its construction method. The mud-bound construction waste composite slab pavement mainly consists of a cultivation soil layer, a coarse sand and gravel layer, a mud-bound construction waste layer, and a rigid slab layer. The cultivation soil layer features grooves, the depth of which is equal to the depth of the plant roots in that layer plus 10 cm ； The coarse gravel layer, the mud-cemented slag layer, and the rigid plate layer are stacked in sequence from bottom to top within the groove ； Among them, the coarse sand and gravel layer is composed of coarse sand and gravelly sand; the cement-lime construction waste layer is made up of cement, lime, and construction waste; the steel plate layer uses steel plates with a certain degree of stiffness. Together, these elements form the subgrade, base layer, and surface layer, ensuring that the load-bearing capacity meets the design requirements and satisfies transportation needs
