Problems solved by technology
[0002] The asphalt pavement needs to be tested before use. The sampling process needs to drill holes in the pavement, and the pavement needs to be repaired after taking it. The common repair method uses asphalt to simply fill the sampling hole. This treatment method has potential safety hazards. After filling The bonding force between the asphalt and the original asphalt is insufficient, and the added asphalt has not been extruded, and the internal voids are large, and the mechanical properties are quite different from the original road surface. Therefore, the main problem to be solved by the present invention is how to improve the mechanical properties of the supplemented asphalt. Improves patching of sampling holes to maintain long service life of asphalt pavements

The invention relates to the technical field of asphalt pavement repairing, and discloses an asphalt pavement sampling and repairing machine which comprises an asphalt storage tank, an asphalt storage cavity is formed in the asphalt storage tank, a fixed outer pipe is arranged on the lower side of the asphalt storage tank, a fixed cavity is formed in the fixed outer pipe, and the fixed cavity communicates with the asphalt storage cavity; by arranging the fixed outer pipe, the movable inner pipe, the asphalt storage tank, the extrusion sliding plate and the like, when the device is used for filling a sampling hole, the movable inner pipe directly extends into the hole, and gradually moves upwards to be separated from the sampling hole in the filling process, so that the sampling hole is filled, and the sampling hole is filled. The injection mode can effectively avoid the situation that asphalt is difficult to inject into the bottom of the deep hole due to too high viscosity.
Description
technical field [0001] The invention relates to the technical field of asphalt pavement repair, in particular to an asphalt pavement sampling repair machine. Background technique [0002] The asphalt pavement needs to be tested before use. The sampling process needs to drill holes in the pavement, and the pavement needs to be repaired after taking it. The common repair method uses asphalt to simply fill the sampling hole. This treatment method has potential safety hazards. After filling The bonding force between the asphalt and the original asphalt is insufficient, and the added asphalt has not been extruded, and the internal voids are large, and the mechanical properties are quite different from the original road surface. Therefore, the main problem to be solved by the present invention is how to improve the mechanical properties of the supplemented asphalt. Improve the repair effect of the sampling hole, so as to maintain a long service life of the asphalt pavement. Cont...
