Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement construction, in particular to an assembled pavement skeleton structure. Background Art

[0002] Asphalt pavement refers to various types of pavement constructed by blending road asphalt with mineral materials. The asphalt binder enhances the paving aggregate's ability to withstand damage from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable surface. Therefore, asphalt pavement is the most widely used high-quality pavement in road construction.

[0003] During asphalt pavement construction, to prevent excessive expansion when the roller flattens the graded gravel, support frames need to be installed on both sides of the roadbed before the graded gravel is laid. These frames block the graded gravel and solidify the surface. However, typical asphalt pavements are relatively long, and their support frames often adopt a modular design. To improve construction efficiency, the support frames must be easily assembled and disassembled. Therefore, a prefabricated pavement frame structure is proposed to address the above-mentioned issues. Utility Model Content
