The invention discloses a high-speed rail ballastless track concrete roadbed slab crack restoration and maintenance material and preparation and application thereof. The restoration material comprises, by weight, 10-20% of nanosilicon dioxide, 4-5% of sodium metasilicate, 1-2% of sodium hydroxide, 1-2% of a cross-linking agent, 0.5-1.0% of a hardening accelerator, 0.01-0.05% of a surface activating agent, 0.2-0.5% of sodium tripolyphosphate, 0.1-0.3% of sodium sulfate, and the balance deionized water. The restoration material can be rapidly condensed and hardened under the drying environment, and has the advantages of high binding power and high permeability, and is convenient to construct, free of toxicity or pollution and capable of achieving rapid restoration and maintenance for a high-speed rail ballastless track concrete roadbed slab.
