Abstract

The invention discloses a repairing agent for cracks on bituminous pavement and relates to the technical field of traffic road repairing. Key point of the technical scheme is that the repairing agentcomprises the following components in parts by weight: 65-80 parts of epoxy resin emulsion compound SBS asphaltic liquid, 6-13 parts of plasticizer, 15-27 parts of 50-70 mesh rubber powder, 3-7 partsof tackifier and 5-9 parts of fiber stabilizer; the epoxy resin emulsion compound SBS asphaltic liquid comprises the following materials in parts by weight: 15-25 parts of epoxy resin emulsion, 30-50parts of cold mixing SBS asphaltic liquid and 1.5-2.5 parts of curing agent. The preparation method for the epoxy resin emulsion compound SBS asphaltic liquid comprises the following steps: adding 30-50 parts of cold mixing SBS asphaltic liquid into 15-25 parts of epoxy resin emulsion while stirring, and then adding 1.5-2.5 parts of curing agent into the mixed solution while stirring, and uniformly stirring, thereby acquiring the epoxy resin emulsion compound SBS asphaltic liquid. According to the invention, the problems of long drying time of repairing agent and long waiting time for restoring traffic can be solved, and the effects of short drying time and quick restoring of traffic can be achieved.

Description

technical field [0001] The invention relates to the technical field of traffic road repair, more specifically, it relates to an asphalt pavement crack repair agent and a preparation method thereof. Background technique [0002] After the asphalt pavement pavement is completed and put into use, pavement cracks will appear due to various factors. Although the initial stage of pavement crack formation has little effect on the use of the pavement, if it is not filled in time, the expansion of pavement cracks will gradually weaken the bearing capacity of the road structure. Stability problems, resulting in network cracks, cracks, potholes and other phenomena, the road bearing capacity is reduced, and the service life of the road is reduced. If the asphalt pavement can be maintained and treated in time when the asphalt pavement has been used for 2 to 3 years or when there are slight cracks on the pavement but the pavement structure is not damaged, the cohesiveness and viscous tou...
