Problems solved by technology

Although the low-temperature fluidity and permeability of asphalt are improved due to the addition of organic solvents in the existing liquid filling materials, the high-temperature stability and elastic recovery performance of the existing liquid filling materials are reduced.
As a result, the filling material of the cold construction method in summer is easy to overflow and is taken away by the vehicle; in winter, the material of the seam tape and seam strip is embedded in the crack under the long-term driving action, resulting in the thinning of the road surface material and reducing the wear force , and the performance of a single structural form reduces the service life of the material

Abstract

An asphalt rubber strip and its preparation and construction methods belong to the technical field of pavement asphalt construction. It is characterized in that it is made of the following components by weight: 70-90 parts of asphalt, 2-10 parts of styrene-butadiene copolymer, 8-15 parts of solvent oil, 1-5 parts of filler, 1-5 parts of stabilizer 5 parts, 0.1-0.3 parts of antioxidant; the solvent oil is one of aromatic oil, coal tar, diesel oil or kerosene; the pitch is petroleum pitch or coal tar pitch. The construction method of the asphalt rubber strip comprises the steps of brushing, dust removal, caulking and seam pasting. The asphalt rubber strip has high viscosity and elongation performance, and can complete the filling of pavement cracks without heating. The construction method of the asphalt adhesive tape takes a short time, can be completed without the assistance of joint filling equipment, and has a firm and durable construction effect.

Description

Technical field [0001] An asphalt glue strip and its preparation and construction methods belong to the field of pavement asphalt construction technology. Background technique [0002] After the asphalt pavement is put into use, the road cracks will occur due to various factors.Although the initial period of the formation of road cracks has little impact on the function of the road surface, if it is not closed in time, the expansion of the road cracks will gradually weaken the road structure bearing capacity.The problem of stability, thus the phenomenon of mesh, cracking, pits and troughs.The road carrying capacity decreases, reducing the life of the road.Therefore, it is an important task for extending the service life of the pavement and reducing the cost of pavement to the pavement cracks. [0003] The existing crack treatment processes mostly use the heat construction method that fills the filling cracking materials into the crack.As the name suggests, the heat construction m...
