Seams in an asphalt concrete coating laid on top of concrete
During the major repair of the concrete layer or during the reconstruction of large areas, seams are necessary in the asphalt concrete coating laid on top of the concrete. "Gutman Konstrakshin" company performs works of any volume and complexity, using its own equipment and a fleet of special equipment with a guarantee of quality and taking into account strict compliance with predetermined deadlines.
In what cases is this service necessary? There are road projects in which the layer of cement concrete does not change, but acts as the top of the base. The upper layer is equipped with the use of asphalt concrete. Then the deformation joints require a special approach, because otherwise cracks will form on the surface, affecting the new asphalt concrete mixture. Seams are cut directly above the seams belonging to the lower level.
There are a number of technological requirements that apply exclusively to this procedure. First, a preliminary binding of the lower seam to the provided base is performed. Secondly, after finishing laying the top layer, the seams that will be applied in the future are marked. Slicing begins only after the hot asphalt cools down. Otherwise, there may be traces of moving stacking equipment.

Thirdly, it is necessary to use a technique that is also suitable for arranging seams in concrete. The carver uses specialized diamond discs designed for use with this particular material. The optimal seam width starts from 1 cm, and a chamfer device in compression and expansion seams is usually not required.
Fourth, after completion of work, preparation is required before sealing. It includes washing, cleaning, blowing and drying. Cleaning the camera with the use of wire metal brushes is combined with the laying of the cord of the seal and the erection of the primer. We provide a full range of services related to reconstruction and road construction.
