System for the avoidance of joints image of a lead according to the installation of a road cap in a road surface

摘要

The present invention relates to a system for the avoidance of joints image of a lead according to the installation of a road cap (1) in a road surface (2), wherein the road cap (1) has a cover (5) and in the installed state in its upper boundary area of the road surface (2) with a sealing means (6) in order to avoid crack formation in the road surface (2) is provided.In this case, a uniform and homogeneous tightly means border (6 '), which is free of depressions, produced in that the road cap (1) at the upper outer edge with a tightly fabricated in this way means ring (7) is provided that the sealing means (6) of the sealing means ring (7) in a temperature range, the rolling temperature of the roads coating deck layer (2') corresponds to, can connect with the latter, that a heat cap (8) is provided, which means the sealing ring (7) in front of a softening by means of the paving protects and in that the heat cap (8) before the rolling of the roads coating deck layer (2 ') is removable, wherein an air gap (9) in the width of the outer wall (10, 10') of the heat cap (8) is produced, so that a heat transfer during the application of the asphalt of the roads coating deck layer (2 '), on the sealing means ring (7) is prevented, and that it is only during the rolling of the air gap (9) by means of the compression of material of the roads coating deck layer (2') closes in such a way that, as a result, the road covering cover layer (2 ') with the sealing means (6) of the sealing means ring (7) to a tightly means border (6') connects.n="23"
