The joint is caused by the shutdown of cold regeneration in construction, so how to solve this problem?
Even if it takes only a few minutes to replace the tank car at each shutdown, a transverse seam will be formed which seriously affects the uniformity of recycled materials. Therefore, the shutdown phenomenon should be reduced as much as possible in the construction. In the inevitable case, the formed transverse joints should be carefully treated.
1. When the construction is started again after temporary shutdown, the whole regeneration unit shall move backward 1.5-2m to reach the regenerated materials, so as to ensure that all materials are treated after construction.
2. During the compaction of the previous section, 4-6m shall be reserved for no rolling, and the next section shall be compacted at the same time.
3. When the regenerator starts to work, all rotors must be cut down to the bottom of the regeneration layer to crush the recycled materials. The forward speed is 0, which makes the reclaimed materials mixed unevenly. Therefore, it is necessary to level the pits and grooves after mixing manually.
The working width of the regenerator is generally smaller than that of the recycled pavement. Therefore, the regeneration of full width road requires multiple operations, resulting in longitudinal joints between several adjacent working surfaces.
Generally speaking, the minimum overlap between adjacent working faces is 10 cm to ensure the continuity of recycled materials at the longitudinal joints, and to avoid the entrainment of non regenerated materials between adjacent working faces.
