Asphalt pavement sticking seam repairing material and asphalt pavement sticking seam repairing belt

Abstract

The invention relates to an asphalt pavement sticking seam repairing material and an asphalt pavement sticking seam repairing belt. The repairing belt is composed of the asphalt pavement sticking seam repairing material, anti-sticking ash powder, a fine sand layer and a backing tape, wherein the asphalt pavement sticking seam repairing material is arranged on the backing tape; an anti-sticking ash sand layer is arranged on the upper surface of the asphalt pavement sticking seam repairing material; the repairing material is prepared from the following main components in parts by weight: 100 parts of petroleum asphalt, 5-15 parts of a modifying agent, 2-15 parts of a tackifier, 0.3-1 part of an anti-ageing agent, 6-20 parts of a softening agent and 40-70 parts of an enhancing agent. By virtue of the scheme, the asphalt pavement sticking seam repairing material can be used for effectively combined with pavement asphalt on the two sides of a previous pavement seam to block and cover on an asphalt pavement seam, so that a roadbed is protected from corrosion; the two sides of the previous pavement seam are connected to prevent the seam from being continually expanded; the connection between the sticking seam repairing material and a previous pavement is enhanced under the rolling of vehicles and the anti-sticking ash sand layer can prevent the sticking seam repairing material from being stuck on wheels.
