Description

Technical Field

[0001] The present invention relates to the technical field of roadbed construction, in particular to a pressure-resistant roadbed structure and a construction method thereof. Background Art

[0002] In the use of road subgrade, the place where the subgrade is most susceptible to wear and tear is the solid line in front of the traffic light, and the location of wear and tear is the same as the location of the wheels. The reason is that when a vehicle brakes after passing a traffic light, due to inertia, the center of the car will tilt toward the direction of the car's movement, causing the front wheels of the car to bear greater force. Ultimately, this force is transmitted to the subgrade of the road, causing the subgrade to deform and wear and tear.

[0003] Therefore, the applicant, based on many years of rich experience in design, development and actual production in the relevant industry, has conducted research and improvements on the existing structure and its deficiencies, and provided a pressure-resistant roadbed structure and its construction method, in order to achieve a more practical purpose.
