Problems solved by technology
However, due to the differences in the asphalt concrete material itself, as well as the design, construction and maintenance level and the external environment, the asphalt pavement often has cracks, looseness, subsidence, cracking, oil flooding, ruts, potholes and other diseases.
The emergence of these diseases has seriously affected the driving speed and driving safety, and shortened the service life of asphalt pavement, resulting in the shortening of the service life of the pavement.
However, the existing repair methods are labor-intensive, time-consuming and labor-intensive, and cannot quickly and effectively repair the pavement

Embodiment Construction
[0027] use Figure 1-Figure 5 A road surface restoration method according to an embodiment of the present invention will be described below.
[0028] like figure 1 and figure 2 Shown, a kind of asphalt pavement repairing method of the present invention, this method comprises the steps:
[0029] Step 1: Clean the road surface to be repaired, and measure and determine the scope and depth of the road surface to be repaired;
[0030] Step 2: After step 1 is completed, the road surface is broken, filled and rolled by the road surface repair device to complete the road surface repair;
[0031] Step 3: In the repair process of Step 2, add asphalt rejuvenator to restore the crushed asphalt, so as to realize the reuse of the original asphalt and save the consumption of asphalt;
[0032] Step 4: After the completion of Step 2, set up obstacle protection, and complete the repair after the road surface solidifies;
[0033] Wherein, the road surface restoration device described in step...

The invention belongs to the technical field of rapid pavement repair, in particular to an asphalt pavement repair method. The method comprises the following steps: cleaning the pavement to be repaired, and measuring and determining the range and depth of the pavement to be repaired; crushing The pavement,stuffing and rolling the pavement repair device to complete the pavement repair; In the repair process, adding asphalt recycling agent to reduce the crushed asphalt, so that the original asphalt can be reused and the consumption of asphalt can be saved. Setting Obstacle protection and completing repair as soon as the pavement solidifies. The invention can realize the rapid repair of the highway pavement, has high working efficiency and low cost.
Description
technical field [0001] The invention belongs to the technical field of rapid repair of road surfaces, in particular to a method for repairing asphalt pavement. Background technique [0002] Highway is an important symbol to measure a country's economic strength and modernization level, and it has an obvious role in promoting national economic and social development. With the rapid development of my country's highway industry, the task of highway maintenance is becoming increasingly arduous. And my country's highway is mainly based on asphalt pavement, and asphalt pavement is widely used in road engineering, from country roads to urban roads, from tertiary roads to expressways, all generally adopt. However, due to the differences in the asphalt concrete material itself, as well as the design, construction and maintenance level and the external environment, the asphalt pavement often has cracks, looseness, subsidence, cracking, oil flooding, ruts, potholes and other diseases....
