Embodiment 1

[0019] Taking 100kg of water for preparing cleaning solution as an example, the method steps for cleaning porous asphalt pavement voids are as follows:

[0020] 1. Vacuum the sundries in the gaps of porous asphalt pavement

[0021] Use a vacuum cleaner to vacuum the clogged sundries in the gaps of the porous asphalt pavement for 15 to 20 seconds, and the vacuum degree of the vacuum cleaner is 21.

[0022] 2. Prepare cleaning solution

[0023] Add 4kg of QW-917 road cleaner into 100kg of water, stir evenly, form foam, and prepare cleaning solution.

[0024] 3. Rinse porous asphalt pavement with high-pressure cleaning fluid

[0025] Spray the cleaning solution with a pressure of 5MPa from a cold water high-pressure cleaner into the porous asphalt pavement after vacuuming for 20 seconds, with an interval of 10 minutes.

Embodiment 2

[0027] Taking 100kg of water for preparing cleaning solution as an example, the method steps for cleaning porous asphalt pavement voids are as follows:

[0028] In step 2 of preparing the cleaning solution, add 2 kg of QW-917 road cleaner to 100 kg of water, stir evenly, form foam, and prepare cleaning solution. In the step 3 of flushing the porous asphalt pavement with high-pressure cleaning fluid, spray the cleaning fluid with a pressure of 3MPa from a cold water high-pressure cleaner into the porous asphalt pavement after vacuuming for 15 seconds, with an interval of 10 minutes, and then use a high-pressure cleaning fluid with a pressure of 8 MPa from a cold water high-pressure cleaner Rinse the porous asphalt pavement with a 25-second flush. Other steps are identical with embodiment 1.

Embodiment 3

[0030] Taking 100kg of water for preparing cleaning solution as an example, the method steps for cleaning porous asphalt pavement voids are as follows:

[0031] In step 2 of preparing the cleaning solution, add 8 kg of QW-917 road cleaner to 100 kg of water, stir evenly, form foam, and prepare cleaning solution. In step 3 of flushing the porous asphalt pavement with high-pressure cleaning fluid, spray the cleaning fluid with a pressure of 7 MPa from a cold water high-pressure cleaner into the porous asphalt pavement after vacuuming for 25 seconds, with an interval of 10 minutes, and then use a high-pressure cleaning fluid with a pressure of 12 MPa from a cold water high-pressure cleaner Rinse the porous asphalt pavement with a 35-second flush. Other steps are identical with embodiment 1.

Abstract

The invention relates to a method for recovering a clearance of a porous asphalt pavement, which comprises the following steps of: carrying out dust-absorption treatment to pollutants in the asphalt pavement clearance, preparing a cleaning solution, flushing a porous asphalt pavement with high-pressure cleaning solution, and the like. A great deal of researches and experiments show that the method can effectively recover the clearance of the porous asphalt pavement, improve the water permeability and various pavement performances of the porous asphalt pavement and prolong the service time of the porous asphalt pavement. The invention can be used for cleaning clearance blockage of the porous asphalt pavement.

Description

technical field [0001] The invention belongs to the technical field of spraying wet or non-spraying road surface to clear the waste on road or similar road surface, and in particular relates to a method for restoring voids of porous asphalt pavement. technical background [0002] At present, the structure of asphalt pavement should not only resist the repetitive action of traffic load, but also satisfy good surface functions. Porous asphalt pavement will inevitably become the development trend of asphalt pavement in the future because of the visibility of road markings in wet weather and at night, improving the skid resistance of wet pavement, and improving the driving safety of the road. These properties of porous asphalt pavement are directly or indirectly related to the porosity. When the porosity is reduced to a certain value, these properties will be greatly reduced or even disappear. Therefore, the porosity recovery of porous asphalt pavement is very important. [0...
