The invention relates to an anti-
rut agent, which is characterized in that the anti-
rut agent is composed of the following materials by weight: 40-50% of trivalent
ferric salt, 40-50% of
synthetic rubber and 10-12% of sulphur stabilizer. A preparation method for the anti-
rut agent is characterized in that the steps are as follows: (1), the
synthetic rubber is smashed to the degree that the
fineness is less than 80 meshes; (2), the smashed
synthetic rubber and the sulphur stabilizer are added into trivalent
ferric salt solution according to the component proportion; and (3), the
mixed solution is stirred uniformly under the normal temperature, so as to obtain the anti-rut agent. The raw materials of the anti-rut agent are obtained easily, the preparation method is simple, the excellent effect can be realized with smaller dosage of the raw materials, the cost is low, the mixing time is short, and the
energy consumption is low; the construction is realized under the normal temperature, so that the construction process is controlled easily, and no
pollution is discharged, thereby improving the high-temperature stability and the anti-rut capability of an
asphalt mixture and realizing higher innovation. The preparation method for the anti-rut agent is simple in operation, is controlled easily and does not cause
pollution.
