The invention discloses a polyurethane urea-rubber composite grouting material for inhibiting/breaking ice on a grooved pavement and a preparation method thereof, and relates to the technical field of grouting materials for roads. The polyurethane urea-rubber composite grouting material is prepared from the following components in parts by mass: 40 to 45 parts of a polyurethane component A, 200 to 210 parts of a polyurethane component B, 50 to 55 parts of a polyurea component A, 50 to 55 parts of a polyurea component R, 14 to 21 parts of an organic solvent, 1 to 3 parts of a catalyst and 150 to 350 parts of rubber particles. The preparation method comprises the following steps: mixing polyurethane and polyurea according to a given raw material ratio, adding an organic solvent and a catalyst, stirring, adding rubber particles, and uniformly stirring to obtain the polyurethane urea-rubber composite grouting material which can be used as a filling material for grooved pavements to achieve the purposes of inhibiting and breaking ice on the pavements.
