We cut out the gate boxes using a specialized machine in a line in a circle. The resulting cavity in the pavement should be cleaned and completely removed from loose elements. Then, the support of the box is rebuilt on the basis of a quick-setting sealing compound. A suitable quick-setting pouring mortar achieves a high increase in strength with respect to time. Place the box for the road grade line on the prepared base. The box is watered with quick-setting mortar in such a way that it only floods the box’s flange. We fill the loss in the road surface caused by the box adjustment with hot mass. Before laying the asphalt mass, sprinkle the substrate with asphalt emulsion on hot under pressure, which will increase the adhesion of the mass to the substrate.
