The invention discloses a low-viscosity high-early-strength polyurethane repair material for high speed railway slab ballastless track filling layer open joint repair. The repair material consists of two parts, namely a part A and a part B, wherein the part A consists of the following raw materials in parts by mass: 100 parts of isocyanate and prepolymers thereof; the part B consists of the following raw materials in parts by mass: 60-80 parts of reactive hydrogen oligomer, 40-70 parts of a plasticizer, 0.5-2 parts of a defoaming agent and 0.1-1 part of an anti-aging agent; and the volume ratio of the part A to the part B is 1:1. The polyurethane open joint repair material has the advantages of low viscosity, high curing speed, high mechanical strength, high adhesive strength, high toughness and excellent durability, can meet the requirements on rapid construction in skylight time and instant traffic service after repair and can be used for rapid maintenance of the operating high speed railway slab ballastless track structure.
