Description

Technical Field

[0001] The invention relates to the technical field of road construction, in particular to a road restoration method. Background Art

[0002] During long-term use, roads may be damaged due to material aging or impact from external objects, which may easily affect driving safety. Therefore, they need to be repaired and restored in a timely manner. After searching, an invention patent with publication number CN115162082A discloses an existing road transverse construction and road restoration method, including: completing the hardening of the expansion area and completing the construction of the planned construction area on the non-expansion area side; merging the temporary municipal road far from the expansion area side to the original municipal road close to the expansion area side, merging the temporary municipal road close to the expansion area side to the expansion area, and completing the construction of the planned construction area of ​​the original municipal road far from the expansion area side; restoring the original municipal road far from the expansion area side, and completing the construction of the planned construction area at the location of the original municipal road close to the expansion area; restoring the original municipal road close to the expansion area side, demolishing the expansion area, and completing subsequent construction. It has the characteristics of short construction period, small impact range, and low construction cost.

[0003] Although this method has the above advantages, it still has the following disadvantages in actual use:

[0004] 1) This method widens the road next to the repaired section and changes the direction of the oncoming lane to divert traffic to avoid affecting traffic. First, the oncoming lane is diverted. After the road is repaired and traffic is restored, the mixed diversion lines are prone to diversion errors. Secondly, the widened part of the road is time-consuming and labor-intensive to dismantle and reconstruct, and cannot be used after dismantling, resulting in a waste of cost and materials.

[0005] 2) The core of this method is to establish an expansion area beside the repair section. However, for single-lane roads and areas with limited road width and where both sides of the road cannot be expanded, this method is limited in effect or makes the cost of road restoration even greater.

[0006] Therefore, it is necessary to provide a method to solve the above-mentioned problems. Summary of the invention
