Abstract
Description
Technical Field
[0001] This utility model belongs to the field of trail technology, and more specifically, it relates to a trail surface structure. Background Technology
[0002] The surface layer of a walkway refers to the layer located above the base layer of the walkway, which is in direct contact with pedestrians or cyclists. The main materials of the surface layer include asphalt mixture or cement concrete, and its main function is to provide good wear resistance, anti-slip properties and aesthetics.
[0003] The existing walkway surface structure is generally constructed by directly pouring it onto the roadbed. However, when the walkway surface is partially damaged, traditional repair methods often involve a complex process: first, the damaged area needs to be precisely cut and removed, and then the pouring work needs to be carried out again. This repair process is not only time-consuming, increasing the uncertainty of the project schedule, but also cumbersome and inefficient. More importantly, the newly repaired walkway surface is often difficult to maintain a completely consistent height with the surrounding original surface, which not only affects the overall flatness and comfort of the walkway, but also damages its aesthetics and lowers the quality evaluation of the walkway.
