[0023] A quick repair method of cement-emulsified asphalt mortar for unit slab ballastless track. The method mainly includes cleaning, sealing, setting grouting openings, joint grouting and edge cleaning. Specifically, high-pressure air is used to clean cement-emulsified asphalt Dust and impurities around the mortar separation gap, and after the separation gap area is embedded with polyethylene foam material, then scrape 2-5mm fast-curing flexible sealing material or spray self-foaming material on the separation gap surface, and then seal it with polystyrene foam. Then set the grouting port by directly inserting the polyurethane pressure-resistant pipe with an inner diameter of 2 to 4mm into the sealing material. The grouting port is set on the interface between the cement emulsified asphalt mortar and the bottom of the track slab or the base / supporting layer. The distance between the grouting ports is 65cm. Place a dial indicator at the four corners of the track plate in the ...
