Technical Field

[0001] The utility model relates to the technical field of expressways, in particular to an expressway roadbed structure that prevents roadbed softening. Background Art

[0002] Expressways, or highways for short, are roads designed for high-speed driving of cars. Expressways have different regulations in different countries, regions, eras, and scientific research fields. According to China's Highway Engineering Technical Standards (JTG B01-2014), expressways are multi-lane roads designed for cars to drive in different directions and lanes, with full access control. The existing expressways use roadbeds for bottom support, and different materials are used for structural connections in different regions.

[0003] However, the existing technology lacks the function of preventing the road surface from softening. In actual use, in a rainy and humid environment, the road surface will be unstable, soften, and partially collapse, which will cause great harm when the speed of the car on the highway is high.

[0004] In addition, the existing technology lacks the function of support and fixation. In actual use, highways need to have good toughness and strength due to their long sections and large number of vehicles. The unstable installation structure of the roadbed material will cause the road surface to deform and the material to become loose. Utility Model Content
