Abstract

The invention relates to a high efficiency resin fissures cementation glue for pitch and cement road surface fissures cementation. The fissures cementation glue comprises the following components by weight percent: 10 to 15 percent of aromatic hydrocarbon, 3 to 10 percent of modifier, 1 to 3 percent of intensifier, 3 to 10 percent of cosolvent, 30 to 60 percent of resin mixture and 10 to 20 percent of heavy traffic pitch. The aromatic hydrocarbon is heated to 60 to 70 degrees centigrade, the modifier is added to be stirred for 30 minutes, the intensifier and the cosolvent are added slowly step by step, the resin and the pitch are added at last, the temperature is kept at 120 degrees centigrade for 30 minutes under stir circumstance, and then the resin fissures cementation glue with excellent performance can be obtained. In the invention, the aromatic hydrocarbon is used to form even mixture among the modifier, the resin and the pitch so that resin group and pitch group are bridged under the action of the modifier. When used on the road surface, the resin exerts the high bondability characteristic and the like. The modifier is used to improve the road performance, as improving softening point, low temperature ductility and the like. At the same time, the invention is good glue material.

Description

technical field [0001] The invention relates to a resin-type joint-filling glue for highway pavement, in particular to a high-efficiency resin-type joint-filling glue used for filling joints on asphalt and cement road surfaces. Background technique [0002] A large number of asphalt or cement is used as the pavement cementitious material for highway pavement. However, asphalt or cement is used as a cementitious pavement, due to the erosion of sunlight, wind, and water in nature, certain performance aging problems will occur; at the same time, due to the inherent characteristics of the material, cement cannot resist thermal expansion and contraction, and asphalt cannot resist comparison. High, concentrated pressure. Therefore, we can often see large or small cracks on the road surface. The existing construction is to directly fill the joints with modified asphalt, and the joints filled with modified asphalt are often damaged due to insufficient bonding force in March, and t...
